I'm going to compare, how windows virtual machines are working in QEMU/KVM environment and IO performance loss. So I want to measure HDD performance in Linux host and Windows VM. Is there any ...
Is there a benchmark program I can use to measure random read speeds of a vps without interference from the kernel cache? Also looking for something where you can change the read sizes say 4k-64k.
After a quick search on Freshmeat I found nothing. Anybody know of a good utility? I normally use time (dd if=/dev/zero of=newfile ...) to test write speed and hdparm -t to test read speed. Thanks. ...
On Linux I would usually use "hdparm -tT device" when I want a quick idea of how an hard drive is performing compared to another; having switched to Mac OS X a few months back I have yet to find ...
