The mode can be write, seq, or rand. seq and rand are read benchmarks, either sequential or random. Before running one of the reading benchmarks, run a write benchmark with the ?no-cleanup option. The default object size is 4 MB, and the default number of simulated threads (parallel writes) is 16. > " This one creates whole objects. You might also look at ceph_smalliobench (in the ceph-tests package) which is a bit more featureful but less friendly to use. Also, fio has an rbd driver. sage > > > ----- Mail original ----- > De: "Venkateswara Rao Jujjuri" <jujjuri@xxxxxxxxx> > À: "aderumier" <aderumier@xxxxxxxxx> > Cc: "Mark Nelson" <mnelson@xxxxxxxxxx>, "ceph-users" <ceph-users@xxxxxxxxxxxxxx>, "ceph-devel" <ceph-devel@xxxxxxxxxxxxxxx>, "Milosz Tanski" <milosz@xxxxxxxxx> > Envoyé: Lundi 27 Avril 2015 08:12:49 > Objet: Re: strange benchmark problem : restarting osd daemon improve performance from 100k iops to 300k iops > > If I want to use librados API for performance testing, are there any > existing benchmark tools which directly accesses librados (not through > rbd or gateway) > > Thanks in advance, > JV > > On Sun, Apr 26, 2015 at 10:46 PM, Alexandre DERUMIER > <aderumier@xxxxxxxxx> wrote: > >>>I'll retest tcmalloc, because I was prety sure to have patched it correctly. > > > > 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. > > > > > > ----- Mail original ----- > > De: "aderumier" <aderumier@xxxxxxxxx> > > À: "Mark Nelson" <mnelson@xxxxxxxxxx> > > Cc: "ceph-users" <ceph-users@xxxxxxxxxxxxxx>, "ceph-devel" <ceph-devel@xxxxxxxxxxxxxxx>, "Milosz Tanski" <milosz@xxxxxxxxx> > > Envoyé: Lundi 27 Avril 2015 07:01:21 > > Objet: Re: strange benchmark problem : restarting osd daemon improve performance from 100k iops to 300k iops > > > > 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. > > > > > > ----- Mail original ----- > > De: "aderumier" <aderumier@xxxxxxxxx> > > À: "Mark Nelson" <mnelson@xxxxxxxxxx> > > Cc: "ceph-users" <ceph-users@xxxxxxxxxxxxxx>, "ceph-devel" <ceph-devel@xxxxxxxxxxxxxxx>, "Milosz Tanski" <milosz@xxxxxxxxx> > > Envoyé: Samedi 25 Avril 2015 06:45:43 > > Objet: Re: strange benchmark problem : restarting osd daemon improve performance from 100k iops to 300k iops > > > >>>We haven't done any kind of real testing on jemalloc, so use at your own > >>>peril.
