* [PATCH] Improved network performance by balancing Rx against other work
From: Peter Chubb @ 2010-03-17 2:55 UTC (permalink / raw)
To: netdev
Hi,
I don't know how many people caught my talk at LCA, but the
slides are now up at http://www.lca2010.org.nz/slides/50036.pdf
The general approach is to restrict the work done in the Rx-side
processing to just 32 or so packets at a time then call
sys_sched_yield() to allow other system processing to get a look in.
Currently, NAPI processing happens in soft IRQ context, and much of it
with interrupts off. Moreover, when a particular poll routine is over
budget, the softirq is reraised --- so the softirq thread keeps
running until the scheduler (which under loaded conditions sees
softirq as a CPU-intensive thread) decides to preempt it. By this
time, more packets are queued than the upper levels can handle in a
reasonable time, killing overall system performance. In addition,
because so much runs with interrupts disabled, real-time performance
sucks.
The results in the talk were for UDP echo, which is a bit easier to
analyse than NFS.
By running the interrupt handler as a separate thread running
SCHED_NORMAL, and getting rid of all deferred work (implicitly
coalescing interrupts) I see around 15% improvement in NFSstone.
What's more, under overload conditions, the standard Linux kernel's
performance droops markedly with increasing load; with this patch, it
remains approximately constant.
Against a 3GHz Celeron, the standard kernel gives a peak of around
8000 NFS ops/sec; as the load increases this drops a little. With this
patch I see 10 000 ops/sec, and less drooping.
NFS over UDP
requests/sec Completed Completed
Generated Std Kernel My patch
5000 5000 5000
10000 8169 10000
15000 7938 10649
20000 7579 11084
25000 7541 10133
Median Latencies at low load are about the same, at around 300usec
(max 7ms). At 10000 applied ops per second, with my patch the median
per-request latency is around 53ms, with the standard kernel 200ms.
CPU usage is around the same in both cases.
I've appended an updated patch (the one I used to present the results
at LCA2010 was extremely hacky, this one is just a bit hacky).
I'm not expecting this to be applied; but please try to reproduce my
results. To do this `properly' is going to mean fairly major surgery
to the NAPI layer, and I'm not yet sure of the right way to do that.
I'd also like a sanity check on my analysis.

netlink: fix NETLINK_RECV_NO_ENOBUFS in netlink_set_err()
Currently, ENOBUFS errors are reported to the socket via
netlink_set_err() even if NETLINK_RECV_NO_ENOBUFS is set. However,
that should not happen. This fixes this problem and it changes the
prototype of netlink_set_err() to return the number of sockets whose
error has been set. This allows to know if any error has been set.
This return value is used in the next patch in these bugfix series.

This patch fixes a unaligned access in nla_get_be64() that was
introduced by myself in a17c859849402315613a0015ac8fbf101acf0cc1.

I can't really explain how the MII and lspci output is being
affected.. However, it's possible that some of the chips supported by
this driver don't actually support 64-bit DMA. Your chip is quite a
bit older than mine (RTL8102E seems to be one of the older, if not the
oldest, PCI-E chipset supported by the driver).
Francois, do you know if that's the case, or do you have any active
contacts at Realtek who can say?
In the meantime, I don't object to reverting the patch for now unless
we get this sorted out quickly..

* [PATCH 2/3] netfilter: ctnetlink: fix reliable event delivery if message building fails
From: Pablo Neira Ayuso @ 2010-03-16 23:30 UTC (permalink / raw)
To: netdev; +Cc: kaber, davem
In-Reply-To: <20100316232247.4185.19426.stgit@decadence>
This patch fixes a bug that allows to lose events when reliable
event delivery mode is used, ie. if NETLINK_BROADCAST_SEND_ERROR
and NETLINK_RECV_NO_ENOBUFS socket options are set.

* [PATCH 1/3] netlink: fix NETLINK_RECV_NO_ENOBUFS in netlink_set_err()
From: Pablo Neira Ayuso @ 2010-03-16 23:29 UTC (permalink / raw)
To: netdev; +Cc: kaber, davem
In-Reply-To: <20100316232247.4185.19426.stgit@decadence>
Currently, ENOBUFS errors are reported to the socket via
netlink_set_err() even if NETLINK_RECV_NO_ENOBUFS is set. However,
that should not happen. This fixes this problem and it changes the
prototype of netlink_set_err() to return the number of sockets whose
error has been set. This allows to know if any error has been set.
This return value is used in the next patch in these bugfix series.

* [PATCH 0/3] several minor Netlink fixes
From: Pablo Neira Ayuso @ 2010-03-16 23:29 UTC (permalink / raw)
To: netdev; +Cc: kaber, davem
Hi!
This patchset contains a couple of fixes for Netlink related stuff. More
relevantly, a path that allows to set ENOBUFS when NETLINK_NO_ENOBUFS is
set (that should not happen). It follows the corresponding fix for
ctnetlink. This patchset closes with one fix for a unaligned access.
Please apply! Thanks!

This fixes a warning generated by one of the bug fixes I
added yesterday.
Applied to net-2.6
bridge: Make first arg to deliver_clone const.
Otherwise we get a warning from the call in br_forward().

I frankly would be OK with seeing the rebuild timer go away
