I've run Ruby apps, including Rails apps, on an XP laptop with little 
trouble.  However, the times that Windows has been painfully slow 
(whether I was running Ruby or not) tended (as best I could tell) to be 
related to networking.


For example, browsing the file system would all too often stall File 
Manager (or File Explorer or whatever it's called) because the OS would 
attempt to resolve mapped  network drives and such.  Seems the time-out 
period is glacial, and until the OS is happy things come to a crawl.

(note: my Win32 SysAdmin skillz ==  Google + MSDN + ad hos experiments)

So, Dr. Anecdotal suggests looking to see if there are mapped drives 
(either actually connected  or not),  references to network printers, 
and so on.
