CentOS 6.x | OpenVZ
I have an openvz VPS host and would like to measure disk read/write speed. Historically, on other physical systems, I've ran
hdparm to collect this information. I haven't been able to get hdparm to work on my openvz host (presumably because of the simfs file system -- maybe something else though).
I've tried the quick-and-dirty method of
dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync and while that works, I'm not quite confident that its accurate. Is there a better way to collect this information?
