Re: Linux

Sysbench semble un bench très spécifique :

In any case, here are a few general comments about sysbench numbers:

Sysbench is a pretty 'batched' workload: it benefits most from batchy
scheduling: the client doing as much work as it can, then server doing
as much work as it can - and so on. The longer the client can work the
more cache-efficient the workload is. Any round-trip to the server due
to pesky preemption only blows up the cache footprint of the workload
and gives lower throughput.

This kind of workload would probably run best on DOS or Windows 3.11,
with no preemptive scheduling done at all.

M'enfin, CFS doit marcher correctement avec ce type de bench. Avec la dernière version de CFS (et glibc) c'est le cas.
