ReiserFS causes CPU high usage?!

ReiserFS causes CPU high usage?!

[Voicu Liviu]

Hi guys,

I have beed working on my gentoo using ext3 for all partitions so then I have 
heard that ReiserFS is much better/faster and indeed it is BUT since I 
switched to ReiserFS I can't do:
Code:
# nice -n -20 emerge some_app_name

The idea is I can do this BUT can't do any thing else...notice to your self 
that I never had this problem while using ext3.

While I have used ext3 I could do "nice -n -10 emerge some_app" and also use 
xfree+xfce4 without problems but with ReiserFS if I do use value less than 0 
for "nice" then the cpu jumps to 100% usage and blocks me out from doing 
something else :-(

Any clue what is going on?
Maybe ReiserFS uses the cpu harder?

(
I have to fix the CPU usage icon_sad.gif I makes me crazy...simple emerge 
loads the CPU to 90 ~ 95%
)

reiserfs is using more CPU than ext2/ext3. It's maintaining its metadata in
balanced tree. Each tree update often requires shifting of some of the data
between or inside of tree nodes. That's where CPU time is going.

Make sure you do not have "CONFIG_REISERFS_CHECK" enabled in you kernel config,
as this enables lots of extra checks in reiserfs code that consume even more CPU.

So, you will not suggest me convert my Pentium2 300 Mhz from ext3 to ReiserFS 
will you?
I really wanna try it but I am afraid that the FS will kill my CPU.

Did not checked this in kernel...will you suggest me try vanilla kernel 
(2.4.20 from kernel.org) without all those patches I have applyed? Maybe this 
will help or not?

using notail option will reduce CPU usage, improve read performance, and 
waste some disk space (still better than ext*).

Already using this :-)
Any way, the system works great but if I change the "nice" value of some 
process then the CPU almost becomes slave of this process.........

out of sheer curiosity: Why you are nicing emerge to -20?!

You are using the O(1) scheduler so I see absolute no need to do so.

Some times I wanna some process to be finnished faster ( if you know what 
gentoo is (FreeBSD alike) ) so during ext3 usage I never had this problem, I 
could do "nice -n -10 emerge mozilla" and still could work on XFree.......so 
do you understand me why I'm woried about it?

[Szabolcs Szasz]

Well, as man nice says:

    "Range goes from -20 (highest priority) to 19 (lowest)."

So why is that such a surprise that CPU goes up
to the sky? Why else -20 is there for? (Or am I
missing something?)

Cheers,
Sab

I use reiserfs on a p-mmx 200MHz, and it runs fine. Also when I renice
processes (like kernel compile).

Your problem sounds strange. Kan you show a top snapshot before and
after the renice?

Btw, dunno about your os, but for example debian start X with nice level
-10, which makes it a bit more responsive when there are little cpu
cycles left.

Try with or without patches, and show the list your .config settings if
the problem still exists.

If that means the compile finishes faster (and you havent said whether or not 
it does) then isnt using more of the cpu a good thing?

Hmm, this sounds too strange. I cannot see why ext3 does not have this problem 
where ReiserFS has a problem, during a kernel compilation.

I have a Celeron, 1,3GHz and it doesn't matter what FS I use, if I nice a 
kernel compilation to -20, I can still work w/o any strangeness.

Now do you understand? I'm even afraid to renice my XFree to -10 cuz I'll

Not right now because the computer is 40 minutes far away of me but I can 
connect via ssh and try to install 'mozilla' for example with nice -10 and 
post here the top snapshot
OK?

Perfect. Can you also post the output of the following to the list?

cat /proc/cpuinfo
cat /proc/meminfo 
hdparm /dev/hda
dmesg

And top output before, during, and after the install please.

In your case, there is no reason to renice the compile to -10, as there
are no other processes which take cpu, and therefore there is nothing to
gain.

I still wonder what could be the reason for the bad response of the
keyboard.

OK :-)
Here at home I have P2 300 Mhz ext3 based.
If I'll do nice -n -20 some_command_here this will not lock my box :-) really

I believe he wants to speed up the compile, for which -10 is ok if there
are other processes which need cpu cycles.

[cut cpuinfo, meminfo, hdparm, dmesg]

All looks ok, although your dmesg misses the last half.

Can you try latest 2.4 without patches?
If you still have problems, please post your kernel config.

Also, please post a 'time make bzImage' so we can compare that.

This is CORRECT, but think, could I use XFree while some preccese has nice 
value -10? I don't think so

Corect, I use X and vmware and JBuilder and XFCE4 so I can renice each 1 I 
want....

OK :-)
Here at home I have P2 300 Mhz ext3 based.
If I'll do nice -n -20 some_command_here this will not lock my box :-) really

You should be able to. But is your X also -10 ?
You said you had problem with that too, but that is really weird as X
would not want 100% cpu.

In an other mail you write that your compiles are very fast. If a new
kernel doesn't solve your problem, and compiles are very fast anyway, I
would say: don't do that then (the renice to -10), or renice to -5 or
some value which does not bother you.

I'm quite sure this is not reiserfs related in any way. Just convert
your p300 to reiserfs and see what happens.

This has _nothing_ todo with ReiserFS.
Use kernel preemption and low latency.
Read all you can about it on l-K and try the usual Internet search engines.
Maybe you can "nice" X to "-16" with the latest O(1) scheduler to get better 
responce. Your GCC (-10) thing is all _WRONG_. It should be "+10" or maybe 
"+19" the max value like I do regularly with my heavy C/C++ compiler runs.
I can run 2 times 20 or more compiler runs in parallel on my former single 1.0 
GHz Athlon and now my dual Athlon MP 1900+.

Run your compiler liek this:

nice +19 make -j20.

I don't want to renice compilation threads, only X to get more responsives 
from it...but this locks me out :-)

So you say, if your box is idle, and you renice your X to -10, you can't
use X? And your input on the prompt is still very slow?

That would be very weird.

I asked you to take the latest 2.4 without patches, but please try the
latest 2.4 with the latest -pre patch. I'm curious to what that one will
bring.

This is what makes me think if I will stick with reiser or not because I need 
x up with vmware and other shit so if i'll try to renice X I won't be able to 
work :-)

What cpu is this? This is not in a 2.4.20 kernel. Are you sure this is
the right .config?
You should use CONFIG_MPENTIUM4 I think.

Why this one?

Did I and others not tell you (quite a few times by now) that it is not
reiserfs related?

i have applyed 13_gcc31-compile-optimizations patch
(this gives me specific march for the cpu i want)

+ifdef CONFIG_MPENTIUM431
+CFLAGS += -march=pentium4 -mmmx -msse -msse2 -falign-functions=4 
- -fprefetch-loop-arrays -maccumulate-outgoing-args
+endif

see?

Re: ReiserFS causes CPU high usage?!

[Hans Reiser]

Nicing a compile to -10 should be expected to make your computer

When using that setup _including VMware_ you simply should not renice 
"each process you want".

Especially VMware (What version?!) remains on disk, transfers from & to 
disk /tmp/ram0 (e.g) and consumes much of CPU-time what is very complex 
to control via nice (in relation to other processes).

Just my experience, best regards,

Manuel

Well, if this is the reason them I'm happy cuz with ReiserFS I don't have to 
wait for IO? Did I uderstand well? Is this ok not to wait for IO and keep the 
CPU "under fire" ? :-)

I think yes, but can't say for sure, and don't count on what strangers
tell you. Besides, 45 minutes sounds like a perfect bike trip. ;-)

Anyway this is very strange.
Perhaps you may want to dig "low latency" patches and give them a try.

Hm, but if you do not renice X, it works ok?

I just noticed:

So if you add X and kde (and other heavy stuff to that), you basically have no RAM,
so probably all the slowdown is from constant swapping.
Just run top when you see the interactive slowdown and look at the swapin/swapout ratio
and swap isage in top & /proc/stat

Already have it:

[*] Low latency scheduling
 [*] Control low latency with sysctl

i just compile kde ( for now I used fluxbox and when I did renice -10 to X, it 
becomed very slow )

So I would be interested in your RAM usage after you run X (even with the fluxbox).
Because now you cannot determine if stuff is slow or not. Is that right?

Are you accessing this box via SSH?  (You said it was 45 minutes away.) 
  If so try "renice -10 3729".

	If ReiserFS were causing your CPU utilization problems, it would look 
more like this:

CPU0 states:  0.5% user, 28.1% system,  0.0% nice, 70.3% idle
CPU1 states:  0.3% user, 28.1% system,  0.0% nice, 71.0% idle

	This is the result when I start a stress.sh -n 50 run, which starts 50 
processes all copying a directory to a ReiserFS filesystem. [dual p3 
733] The numbers vary, but the system number is usually higher than just 
a few percent.

	Your system time is only 0.3%, but your user time is 99.4%. It's your 
userland that's taking all your CPU time. There's a large number of  -10 
nice'd processes in there: The result is that those processes get 
scheduler priority, and things that you're looking for interactive 
response from won't get it.

	I noticed that someone further down the list mentioned that your 
slowdown may be sshd not getting enough CPU time. This seems much more 
likely.

	To answer your other question about ReiserFS on a p2 300: I have a 
closet server running with a few hundred GB of ReiserFS filesystems on 
it, acting as an NFS/Samba server, handling internal web traffic, etc.. 
It's got cycles to spare, and it's only a Celeron 300A.

Re: ReiserFS causes CPU high usage?!

[Vladimir Karavelov]

Hi all,
Does anybody remember that P4 CPUs has a weird thing inside them which slows
down the CPU when it overheats? P4 at 1.5 GHz was for a very little time in
the market and as far as I remember it was mainly as tray, not a boxed
product  (i.e. without original Intel cooler).
I think you must get a trip to the PC and check cooling.
Moths ago I had a problem with P4 PC with stopped cooler. Symptoms was
almost the same.

Vladimir Karavelov

This is what I'm talking about baby :-)
Now I have converted my Pentium2 300Mhz to ReiserFS and all goes just sweet, 
works like a charm....no matter what value I give to "nice" it doesn't lock 
me out of the box.
