I recently upgraded my FreeBSD machines from 6.0R to 6.1-STABLE
I noticed a pleasant surprise - improved disk IO!
In 6.0R best sequential throughput I ever saw was 170 MB/s (32k block
size reads on an 4G file). In 6.1-STABLE I'm seeing 190 Mb/s (32k block
size reads on an 4G file).
The machine in question is a Supermico P3TDER with 2G RAM, a 3Ware 7506
and 4 Maxtor 6Y080P0 RAID0.
So anyway - very nice.
Best wishes
Mark
