Virtual Machine slow for no obvious reason

hi guys,

i having problem 1 of virtual machines in seems go extremely slow, no discernable reason. example, , import our crm system should take under minute take say, 60 minutes on server. frustrating thing vm "seems" healthy. cpu utilisation example low, disk activity under 1mb/ps during import. things opening sql server management studio take long time.

it's though server fine, every operation taking 10 times longer expect no discernable reason.

the physical machine seems fine. it's cpu , disk usage metrics seem low , more importantly host seems responsive, unlike vm.

my problem is, don't know how diagnose problem if usual metrics @ either low or perhaps being misleading.

does have suggestions on might or how can diagnose actual issue is?

if helps, physical machine is:

windows server 2008 r2 64bit
core 2 duo e8400
8gb of ram

the vm
windows server 2008 r2 64bit
core 2 duo e8400 (single vm processor only)
4gb of ram

many thaks can share advice!

hi!

as first step uninstall any antivirus software (if present) installed on vm , assign second cpu vm, comparison.
