Pardon me for butting in here... If you're running 512Mb RAM I don't see any reason to use VM at all. However, if you do keep VM enabled, I always recommend setting the min and max size the same. That keeps the swap file from getting fragmented. Unless you're running background applications while you're running PTLE the VM settings should have no effect on performance. If I remember correctly, the Digi engineers have stated that PTLE makes absolutely no use of VM. So unless Windows is using VM for some other task, the settings make no difference in PTLE. I've tried PTLE with and without VM enabled and have noticed no difference either way. Just my $.02 Mike
