Check out how much L2 cache you have in the machines - it could make a huge
difference.

Lost mouse clicks are definitely not a Win32 issue - it happens on all
machines that are slow enough. The events are received by the VM but Morphic
just does not poll often enough to get the mouse clicks (e.g., when the
mouse gets down and up inbetween two poll cycles you have a lost mouse
click).

I'm not sure about the long pauses but I suspect that this is no Win32 issue
either. I'd recommend looking at the image side and try to figure out if the
problem might be GC related (wild guess: having a big image and not enough
memory might cause the system to swap like hell on full GCs).
