I don't know the state of current software, because I haven't tried
recently, but when I set up my student crystallography workstations a
few years back I noticed many packages (e.g. EPMR, Phaser) that had
potentially long run times (where it is really noticeable) would run on
the identical hardware about 2-3 times faster in Linux than in Windows
XP. Memory swapping wasn't the issue. I was astounded there could be
that much overhead in Windows. A Linux VM on a windows machine being
faster than native Win7 is pretty weird, though.

Most peculiar....although I think but I do not know whether the linux
binaries are 64 bit
I don't think that address space is the issue here if they are.
Maybe the paranoia-checkers in windows slow everything down
although I did not see any resources overwhelmed...
