I don't know the actual size of small io. And what's ceph version you used.
But I think it's possible if KeyValueStore only has half performance
compared to FileStore in small io size. A new config value let user
can tunes it will be introduced and maybe help.
All in all, maybe you could tell

Hi Gregory,
I checked again and again each line change about spill out codes,
still failed to find anything wrong.
I ran ceph_test_rados then activate scrub process several times
locally, nothing unusual. I'm familiar with teuthoghy jobs, maybe we
can find the common thing among fail jobs.

Hello Ceph-developers,
at the moment we are doing some performance testing of Ceph v0.72.2 on ContOS
6.5, 64 bit. He have found, that Ceph from official RPM works faster that one
which was compiled ourselves from sources. Do you know what compiler flags and
configure options are actually used
The compiler flags are in the source RPM, is that correct?

Hello Daniel,
thank you for rapid response. ceph.spec file from the SRPM contains following
lines:
...
export RPM_OPT_FLAGS=`echo $RPM_OPT_FLAGS | sed -e 's/i386/i486/'`
%{configure}
I believe the defaults for that come from the redhat-rpm-config package
