yes, I'm pretty sure I'm hitting the tcmalloc bug since the beginning.
I had patched it, but I think it's not enough.
I had always this bug in random, but mainly when I have a "lot" of concurrent client (20 -40).
more client increase - lower iops .


Today,I had try to start osd with TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES=128M ,
and now it's working fine in all my benchs.


That's a pretty major
performance swing.  I'm not sure if we can draw any conclusions about
jemalloc vs tcmalloc until we can figure out what went wrong.

 From my bench, jemalloc use a little bit more cpu than tcmalloc (maybe 1% or 2%).
Tcmalloc seem to works better, with correct tuning of thread_cache_bytes.


But I don't known how to tune TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES correctly.
Maybe Sommath can tell us ?

Ok, just to make sure that I understand:

tcmalloc un-tuned: ~50k IOPS once bug sets in
tcmalloc with patch and 128MB thread cache bytes: ~195k IOPS
jemalloc un-tuned: ~150k IOPS

Is that correct?  Are there configurations/results I'm missing?

Hi Alex,

Is it possible that you were suffering from the bug during the first
test but once reinstalled you hadn't hit it yet? That's a pretty major
performance swing. I'm not sure if we can draw any conclusions about
jemalloc vs tcmalloc until we can figure out what went wrong.

Ok, I really think I have patched tcmalloc wrongly.
I have repatched it, reinstalled it, and now I'm getting 195k iops with a single osd (10fio rbd jobs 4k randread).

So better than jemalloc.

Hi,

also another big difference,

I can reach now 180k iops with a single jemalloc osd (data in buffer) vs 50k iops max with tcmalloc.

I'll retest tcmalloc, because I was prety sure to have patched it correctly.

We haven't done any kind of real testing on jemalloc, so use at your own
peril. Having said that, we've also been very interested in hearing
community feedback from folks trying it out, so please feel free to give
it a shot. :D

Some feedback, I have runned bench all the night, no speed regression.

And I have a speed increase with fio with more jobs. (with tcmalloc, it seem to be the reverse)

with tcmalloc :

10 fio-rbd jobs = 300k iops
15 fio-rbd jobs = 290k iops
20 fio-rbd jobs = 270k iops
40 fio-rbd jobs = 250k iops

(all with up and down values during the fio bench)


with jemalloc:

10 fio-rbd jobs = 300k iops
15 fio-rbd jobs = 320k iops
20 fio-rbd jobs = 330k iops
40 fio-rbd jobs = 370k iops (can get more currently, only 1 client machine with 20cores 100%)

(all with contant values during the fio bench)

Hi,

I have finished to rebuild ceph with jemalloc,

I got a constant 300k iops for the moment, so no speed regression.

I'll do more long benchmark next week.

If you have the means to compile the same version of ceph with
jemalloc, I would be very interested to see how it does.

Yes, sure. (I have around 3-4 weeks to do all the benchs)

But I don't know how to do it ?
I'm running the cluster on centos7.1, maybe it can be easy to patch
the srpms to rebuild the package with jemalloc.

In some ways I'm glad it turned out not to be NUMA. I still suspect we
will have to deal with it at some point, but perhaps not today. ;)

Hi,
I'm hitting this bug again today.

So don't seem to be numa related (I have try to flush linux buffer to
be sure).

and tcmalloc is patched (I don't known how to verify that it's ok).

I don't have restarted osd yet.

Maybe some perf trace could be usefulll ?

Hi,

I feel it is due to tcmalloc issue

Indeed, I had patched one of my node, but not the other.
So maybe I have hit this bug. (but I can't confirm, I don't have
traces).

But numa interleaving seem to help in my case (maybe not from
100->300k, but 250k->300k).

I need to do more long tests to confirm that.

Hi Alexandre,

We should discuss this at the perf meeting today. We knew NUMA node
affinity issues were going to crop up sooner or later (and indeed
already have in some cases), but this is pretty major. It's probably
time to really dig in and figure out how to deal with this.

Note: this is one of the reasons I like small nodes with single
sockets and fewer OSDs.

In this case , I can reproduce ios going from 85k to 300k iops, up

now setting

and starting osd daemons with

numactl --interleave=all /usr/bin/ceph-osd


I have a constant 300k iops !


I wonder if it could be improve by binding osd daemons to specific
numa node.
I have 2 numanode of 10 cores with 6 osd, but I think it also
require ceph.conf osd threads tunning.

Can you force the degenerate case using numactl? To either affirm or

Hi,

I was doing some benchmarks,
I have found an strange behaviour.

Using fio with rbd engine, I was able to reach around 100k iops.
(osd datas in linux buffer, iostat show 0% disk access)

then after restarting all osd daemons,

the same fio benchmark show now around 300k iops.
(osd datas in linux buffer, iostat show 0% disk access)


any ideas?
