You didn't say what 'network speed' you measure.

In any case, such a difference is to be expected. WinXP
accesses a simulated network card and that simulation
carries a huge overhead.

You can get "paravirtualized" network drivers for
Windows with the commercial XenEnterprise version.

I measured the speed to download
ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-3.1/i386/binary/kerne
l/netbsd-GENERIC.gz.

For the case of guest NetBSD, downloaded it to /tmp (hosted
drive).
For the case of native WinXP, download it to desktop (local
drive).
For the case of guest WinXP, download it to desktop (hosted
drive).
NetBSD used /usr/bin/ftp.  WinXP used Opera 9.21.

That's make sense.  I was just wondering how other people
feel and what other people are doing for their guest WinXP.
Maybe I should try that commercial version.  Thanks for the
info.
