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
