For the sake of testing, I booted into my Vista Home Premium partition 
and installed the latest Lilypond binary from the download page.  I ran 
a lilypond file once and it took about 90 seconds, then ran it a second 
time and it took more than 60 seconds.  The same file on Linux compiles 
in less than 2 seconds.  Honestly I don't know how anyone uses Vista as 
their main OS.  This is a reasonably powerful laptop less than 6 months 
old with 2GB of RAM and a dual-core processor.  I have all the aero eye 
candy disabled and it still runs 10x slower than the 8-year-old Gateway 
box in my office running Ubuntu 8.04.  Man.  Glad to be back on the 
Linux side :)
