The same issue occurrs e.g basic write test on both linux host or M$ with cygwin: "dd if=/dev/zero of=./raw bs=1024k count=100" host(HP DL380 G5 SCSI SAS, RAID 5) = 300MB/s, Win2003 Guest = 9MB/sec. Now I have seen posts saying raid 5 is slow (which doesn't make sense, oh I already checked the partition alignment thing i.e. performance but this didn't cure yes it is better but a red herring)?? so I tried virtualbox to see if I was going mad and as much as software dev guys like to get you crawling all over your hw config I am sceptical as I have seen this on ide,raid, sata etc... amazingly virtualbox compiled on ubuntu host hardy heron 8.04 actually massively outstripped my Host OS on disk write performance????? how is that possible... I don't mean on one test but 6+ tests!! This was to confirm that it was/wasn't vmware problem which it so far clearly is... ironically as i don't have a support contract i am unable to troubleshoot with vmware....Someonehttps://www.blogger.com/profile/10948820056767083540noreply@blogger.com
