What also affects the performance is the performance of the operating systems process managament and memory management. Linux does a pretty good job with memory management, and this can be seen when windows apps are run with wine.
Benchmarks in the past have shown that cpu-dependent operations are equally fast, memory intensive ones are faster in wine, while graphics(2D gdi) are much slower in wine. In this case, I think, background processes make the difference. Was the windows box free of malware? Any firewall, virus scanner, quick launch tray applets running?
