Yes this is a very interesting issue.

I'll test this out myself. I am running a 64bit Vista laptop but that part actually doesn't matter. I have VMware running with centos 5.2.

I can definitley help verify how quickly the script runs because if I can get it at around 60-80ms as well like you, then to me that would be great benchmark speeds since it's running on virtualized OS...

I'll let you know what I discover...
