SMP performance degradation with sysbench

[Lorenzo Allegrucci]

Hi lkml,

according to the test below (sysbench) Linux seems to have scalability
problems beyond 8 client threads:

Hardware is an 8-core amd64 system and jeffr seems willing to try more
Linux versions on that machine.
Anyway, is there anyone who can reproduce this?
