The experimental version of Bonnie++ (1.9x) displays the worst-case latencies of all operations. It might shed some light on these issues. If your suspicion is correct then a large part of the performance loss would be on a few operations (maybe even a single operation), in which case the latency reported by 1.9x would be extreme. -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page
