Testing Report: Server: HP DL785G5 , AMD Opteron 8356 * 8 ( 32 cores ) , 16G RAM DB: PostgreSQL 8.3.3 ( install from ports , default option ) Test tool: super-smack ( install from ports ) Disk: 146G SAS * 2 ( RAID 1 on HP P400 )
OS kernel: Just change the 4BSD to ULE , and increase the MAXCPU to 32.
