Hi Paul, thanks for your suggestions (some of them I've applied before starting any consideration, like disabling all on-disk caches or controller buffers) I'll try next monday. Anyway, the fact is that using the same hardware configuration (raid1+raid10) I saw that a centos 6.x outperformed freebsd 9.1. Another test I made yesterday was: on the same hardware I installed vmware esx 5.x and created a vm with centos inside it. The result was really impressive: the centos vm outperformed the 'real' freebsd 9.1 too and checking vmware performances graphs I didn't see any huge need for a massive throughput (I saw values from KBps to 10MBps), instead I saw a big use of CPU (using OLTP tests with a concurrency of 32 threads it's performaces began to slow down). I don't know is using some magic value for HZ or setting some trick with scheduler, I could gain something: I hope so, because I don't want to "pinguinate" my farm :) Thanks, d.
