I wonder why this qualifies as a "kernel bug". This is a well known problem.

At least, current kernel versions no longer block softirq for long periods while doing this...

cat /proc/net/tcp is slow and deprecated, since it uses a O(N^2) algo.

tcp hash table size might be a litle bit too large for typical setups (few tcp session, even on a 16 GB machine)
Unfortunatly it is fixed at boot time and not dynamic (yet)

You can :

1) Boot your machine with a boot cmd "thash_entries=1024" to reduce size of TCP hash table
(typical size on a 4GB machine is : TCP established hash table entries: 262144 (order: 10, 4194304 bytes))

(max size is 524288 entries for machines with >= 8GB memory if no "thash_entries=..." specified, since October 2007
see http://kerneltrap.org/mailarchive/linux-netdev/2007/10/26/359198 )

2) Switch to netlink interface instead of /proc/net/tcp[6] legacy file.
 Example : netstat -N
   http://www.ducksong.com/misc/netstat-netlink-diag-patch.txt

3) Use both 1) & 2) :)

4) Submit a patch to dynamically grow tcp hash table :)

http://kerneltrap.org/mailarchive/linux-netdev/2007/11/1/376907

Time difference between /proc/net/tcp and netlink on a 4GB x86_64 machine :

# dmesg | grep "TCP established hash"
TCP established hash table entries: 262144 (order: 10, 4194304 bytes)
# time cat /proc/net/tcp >/dev/null

real    0m0.091s
user    0m0.001s
sys     0m0.090s
# time ss -n >/dev/null # ss uses netlink interface

real    0m0.022s
user    0m0.000s
sys     0m0.022s

No its not, /proc/net/tcp may be slow in general but not *this* slow ...

As quoted above my idle x86_64, using the exact same hash table size, running 
2.6.27-rc2.git1 uses 0.520 seconds for that same command, thats a difference of 
more then a factor 50 !!

This is not about /proc/net/tcp not being fast, this is about it haven gotten 
slower by a factor of 50!

Also notice that this slowdown does not happen on i386.

Anyways I'll try 2.6.27-rc4 and report back with its results.

Regards,

Hans

And your .config files on i386 and x86_64 are ? 

Some configuration options can slow down all lock/unlock operations (CONFIG_SMP, CONFIG_PREEMPT, CONFIG_PROVE_LOCKING, CONFIG_DEBUG_SPINLOCK, CONFIG_NR_CPUS ...)

If you TCP hash table has 512.000 slots (I am just guessing, you didnt provide this information), it can make a huge difference.

Yes, please, but nothing really changed in this area in the recent times...

We added some checks so that softirqs can preempt us.
Latencies used to be very high, and are now bonded, at the price of potential slowdown for the /proc/net/tcp reader.

I did provide that information: "using the exact same hash table size" and then 
quoting your first mail in this thread:
"TCP established hash table entries: 262144 (order: 10, 4194304 bytes)"

I'm afraid that atleast the Fedora rc4 build won't boot on my machine ...

Slowdown as in 2x or 4x as slow I presume, not 50x ?

I dont know, you tell us 50x, but nowhere I saw your numbers on i386,
nor the amount of memory of your test machine.

One important thing to remember is that on i386, LOWMEM is less than 1GB, 
so a 4GB server will give different hash sizes depending on being 32 or 64 bits.

With a 32 bits kernel:

# dmesg | grep "TCP established"
TCP established hash table entries: 131072 (order: 8, 1048576 bytes)
# time cat /proc/net/tcp >/dev/null

real    0m0.025s
user    0m0.000s
sys     0m0.017s


While on a 64 bits kernel :

# dmesg | grep "TCP established hash"
TCP established hash table entries: 262144 (order: 10, 4194304 bytes)
# time cat /proc/net/tcp >/dev/null

real    0m0.091s
user    0m0.001s
sys     0m0.090s 

So I see a 3x on my machine, not a 50x as you ?

My machine has 2 Gb of memory, but that is not really relevant as I'm not the 
reporter of the problem (but I can reproduce it) I'm only in the loop because I 
maintain the gkrellm package in Fedora which exhibits this problem. Also I gave 
you no i386 numbers on the same machine because I don't have an i386 install 
readily available on this machine.

Now you can spin this anyway you want, but lets cut to the chase, gkrellmd 
which is a system monitoring daemon reads /proc/net/tcp and /proc/net/tcp6 3 
times a second, with slightly older kernel this used to give a CPU load of
2-3% on x86_64 now it gives a load of 50-70% (on my test machine with a whole 8 
tcp connections open).

Now you can wing it any way you want, but this is a serious regression. I don't 
want to go to lkml and start shouting regression REGRESSION regression, but 
given the treating and enormous amount of help I've received sofar (and 
remember I'm only the messenger I didn't write nor use gkrellmd) I'm tending 
towards starting shouting regression on lkml, as atleast there this seems to 
get some attention.

Hans

Last time I checked, one doesn't throw threats at people when they

I'm sorry, but I didn't have the feeling I had many options left. I've reported 
a serious performance regression and all the answer I've been getting sofar is: 
"well if that is slow don't do that you silly" which is anything but a 
satisfying answer.

Anyways as said I'm just the man in the middle, people are hitting this 
performance regression in real life scenarios. I've done my best to make this 
regression clear and known to you, and now I'm done with this thread, please 
remove me from the CC for further replies.

Eric said merely that applications can get better performance by using
the netlink socket dumping interfaces.  It was "for your information",
rather than being suggested as a fix for the bug.

People have given other forms of useful feedback as well, and the bug
seems to be being looked into.

That looks like a factor of 5 to me, not 50.

SUSE had an old patch for this which unfortunately got rejected 
some time ago for some bogus reason.

The reason why it's so slow is because the hash table walk
takes a read lock for each bucket, which is just not fast.
On some architectures like POWER it is even slower than on x86.

The patch simply skipped that for empty buckets.

I append the old patch (haven't checked if it applies
to an recent kernel)

Skip empty hash buckets faster in /proc/net/tcp

On most systems most of the TCP established/time-wait hash buckets are empty.
When walking the hash table for /proc/net/tcp their read locks would
always be aquired just to find out they're empty. This patch changes the code
to check first if the buckets have any entries before taking the lock, which
is much cheaper than taking a lock. Since the hash tables are large
this makes a measurable difference on processing /proc/net/tcp, 
especially on architectures with slow read_lock (e.g. PPC) 

On a 2GB Core2 system here I see a time cat /proc/net/tcp > /dev/null
constently dropping from 0.44s to 0.4-0.8s system time with this change.
This is with mostly empty hash tables.

On systems with slower atomics (like P4 or POWER4) or larger hash tables
(more RAM) the difference is much higher.

This can be noticeable because there are some daemons around who regularly
scan /proc/net/tcp.

Original idea for this patch from Marcus Meissner, but redone by me.

Umm, 0.4 to 0.8 seconds is on average _slower_ than 0.44 seconds.  Did you

Yes noticed that too -- i think it must have been .04-.08 and the zeros
got lost somewhere. I remember that it was significantly faster. It's really 
a benchmark how fast an read lock aquire/release is, but even on 
the best systems it's quite slow compared to lockless code.

FWIW I redid the benchmarks now and it's 0.046s (without) to 0.005s (with

I do wonder if having large hash table actually helps? When TCP hash
table gets too big, it means every lookup is a cache miss. Assuming
a busy server with 2000 connections and perfect hash. On a 4G mem x86-64
we are doing 512K hash entries which is ridiculous. Something like 64K
entries is more than enough.

That's true, but it's nearly guaranteed to only be a single cache miss
at worst (if the hash function is working) compared to potentially
multiple ones if we sized it too small.

I really see the only way to move forward is to dynamically size the
thing.  And nobody has been strong enough to implement that yet :)

You are right. For TCP hash table thats probably hard to implement.

But for route cache, it is probably doable since we added the rt_genid
thing in commit 29e75252da20f3ab9e132c68c9aed156b87beae6 
([IPV4] route cache: Introduce rt_genid for smooth cache invalidation)

If we add a hash table for each "struct net" (net->ipv4.rt_hash_table),
we then could do something sensible when an admin writes to 
/proc/sys/net/ipv4/route/hash_size or at rt_check_expire() time, if
hash table is found to be full...

1) Instead of using alloc_large_system_hash() at boot time to allocate
   rt_hash_table, use a plain vmalloc()
Initial hash size could be small (one page) unless "rhash_entries=xxx" boot parameter says otherwise.

2) If an admin writes a new value to /proc/sys/net/ipv4/route/hash_size :
- Allocate a new table with vmalloc()
- Change the net->ipv4.rt_genid and net->ipv4.rt_hash_table
- Old table contains obsolete entries, rt_free() them all.
- vfree() old hash table, now empty.


3) In rt_check_expire(), adds some metrics to trigger an expand of the
  hash table in case we found too many entries in it.

The synchronization and implementation is not a problem for
the route cache, I implemented this eons ago.

This is the problem and why I didn't just commit the patch I had back
then.

We could not define a reasonable way to trigger hash table growth.

GC attempts to keep a resident set of entries in the cache, and these
heuristics are guided by the table size itself.  So if you grow the
table too aggressively this never has a chance to work.

You want to respond dynamically to traffic in a reasonable amount of
time, but you don't want to get tricked by bursts of RCU effects.

We never came up with an algorithm that addresses all of these
issues.

Maybe because of overcomplicated algos in net/ipv4/route.c, and
mixing "number of entries in cache", and "hash table size" things...

Fact is that nobody wants to have eight elements per hash bucket,
especially in case of DDOS.

Right, but we also use process context processing instead of plain
timer soft irq things, so at least RCU effects should now be OK.

But it is exactly what we want to use to create equilabrium
when the size is large enough.

Of this there is no doubt.  But also, nobody wants to use 1GB hash
table simply because of poorly implemented interactions between GC and
hash table growth :-)

It was a series of patches I started posting in August 2006:

There was a bunch of discussion, the locking and synchronization
were worked out but the resize logic was not.

Sure, but we have /proc/sys/net/ipv4/route/max_size, so hash table size would be
at most (sizeof(void *) * max_size) of course.

The alternative would be to use some kind of cache optimized
tree. While they have in theory more steps if you assume that
the upper levels of the tree are very small and usually are cached
these steps could be very cheap.

Trick question? 

It fixes an old performance problem at least. I'm not aware 
of any new ones in this area because the code in this 
function hasn't changed since I last looked.

> I really doubt it Andi, so please don't use this as an
> opportunity to toot your own horn, thanks.

First I'm not posting patches to "toot my horn" (whatever
you mean with that), but to improve Linux. Please do not
insinuate anything else. Thank you.

Then the patch is still useful and makes sense IMHO. I just
checked and it applies to 2.6.27-rc4 and boots and seems
to still work from a quick check. I expect it would
resolve the problem of the Fedora bug reporter.

Please reconsider. The patch is a straight 
forward optimization of a function that does something
dumb. Doing hundred thousands of atomic operations
unnecessarily (in most cases the hash table 
is mostly empty) just doesn't make much sense.

And no "use rtnetlink" is also not the answer, because
rtnetlink does nothing to fix the extreme cost of the 
full hash table walk if you just want to see all connections.

I'm appending the patch again. Only difference
is that it is rediffed to 2.6.27-rc4 to avoid fuzz
and I redid the benchmark numbers (this time hopefully
without missing zeroes)

That's exactly what this thread is about, things got slower for
some reason even though nothing specifically changed in this area.

I wonder if indirectly something changed in how the hash table
allocator code down in mm/*.c works, perhaps it's taking NUMA
into account differently now?

I reread the original bug and it says nothing about a regression
(unless I'm blind). I think the reporter just ran into the slowness that
was pretty much always there[1] (and which my patch improves)

-Andi

[1] ok it got more noticeable over time because people 
have more memory than they used to have, which made
the hash table bigger.

It's a regression compared to older kernels.  It got slower by a
factor of 5 or something like that.

Not really, I suspect commit (a7ab4b501f9b8a9dc4d5cee542db67b6ccd1088b 
[TCPv4]: Improve BH latency in /proc/net/tcp) is responsible for longer delays.
Note that its rather old :
Date:   Sun Jun 10 17:33:08 2007 -0700


We used to disable bh once, while reading the table. This sucked.

In case machine is handling trafic, we now are preemptable by softirqs
while reading /proc/net/tcp. Thats a good thing.

By the way, I find Andi patch usefull. Same thing could be done for /proc/net/rt_cache.

Yes, that would account for it, good spotting.

Fair enough.  If you can cook up a quick rt_cache patch I'll toss it and
Andi's patch into net-next so it can cook for a while.

Thanks. Here's a little followup patch that implements the same
optimization for inet_diag/ss.

Well, first patch I would like to submit is about letting netlink being able to be 
faster than /proc/net/tcp again :)

I'm not sure it's worth it in this case.  A rcu_read_lock() is a nop
(on non preemptible kernel) to very cheap (non atomic increment/decrement in 
cached task_struct) 

If you really wanted to make it faster I think a better strategy
would be to not take it every bucket, but maybe only every 100th
or so. That would still keep preempt off times reasonably low, but
even help when the table is filled. But not sure it would 
be even measurable, really it should be quite cheap.

It's not one, it's at least two such increments, plus function calls,
state checks, etc. since this is rcu_read_lock_bh().

I'm very happy to see some progress on this and this leading to even more

And now you don't even want to follow the discussions about us fixing
