Have you tried simply pulling the power while running your virtual setup? ForceWrite off gives a substantial improvement on windows and personally I would be suspicious of how ANY virtual setup is handling that. In my tests, running windows and linux directly on the same hardware I have yet to find any windows setup which is faster than linux when run directly on the same hardware. I've currently got W7 and Linux dual boot on my laptop, and I see backup time half the time on the linux install. When Running the Apache/PHP/Firebird stack, linux is a good 4 times faster. So personally I'll be staying with linux for the key support servers :) -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk// Firebird - http://www.firebirdsql.org/index.php
