What happens to a copy of that VM that doesn't have snapshots taken at all?
Just to rule out that taking snapshots and deleting them is the same as 
no snapshots at all.
(I would go for a totally new VM but thats my own paranoia ;-) )

One other thing which isn't applicable to your setup if I'm right is 
that with VMware Server you can set a couple of options that in our case 
sped up things enormously.
Lets look what I set ....

sched.mem.pshare.enable = "FALSE"
mainMem.useNamedFile = "FALSE"
MemTrimRate = "0"

I think the last two are the real ones but don't know if there is 
anything like it with ESX.
