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).
Would have been even better if I'd spelled "sequential" correctly in the
subject :-(...
I'm also seeing sequential write speed increasing from 120Mb/s to 140Mb/s.
I did wonder if this increased IO throughput is what is triggering the
posts about data corruption in 6.1 - i.e. more throughput means more
heat to dissipate!
Cheers
