4.94 sec   WinXP SP2, single Pentium M, 1.7GHz, 512MB
            1-click installer

2.32 sec   Ubuntu 5.10, single Pentium M, 1.7GHz, 512MB
            built with default build options

I took the best run out of 10 or so on each platform. Not building the 
windows version with architecture specific options might account for 
some of the difference.
