It's difficult to judge the performance of the v1.0 release version by running the v4.1 beta release. In addition, the Windows version in v4.1 beta isn't as well tuned as the Mac OS X version ... the latter had about a year's more development/optimization time when the Windows version was released and they haven't posted more than one Public Beta version update for the Windows product, while there were at least three for the Mac OS X version. I suspect they've been tuning and testing the Windows version rather a lot more than is visible with the public beta.
There is far greater variability in quality and performance between hardware platforms in the Windows marketplace compared to the Mac OS X marketplace. I try to keep at least 20-30% free space on my working system's boot drive for best performance. That's what all the backup data drives are for. ;-) Both Windows XP and Mac OS X are virtual memory OS systems and do a lot of back and forth to the drives when using large, complex image processing applications. Total RAM, speed of the drives and free space all combine to influence performance in big ways. Just for reference with Lightroom v4.1 Beta ... All my systems are running Mac OS X v10.4.8. - Running on a PowerMac G5 2.0Ghz DP with 3G RAM and a 500Gbyte drive with 200Gbyte free space. I've been using Lightroom v4.1 beta for two months on a regular basis. Last import was 8500 DNG files, imported by reference. That took about 45 minutes, complete. Total number of files in the Library now is around 28,000. I've seen no slowdowns and performance switching image files is pretty snappy, all controls operate smoothly and without hesitation. - Running on a Mac Book with 2.0Ghz Intel dual core and 2G RAM, 60G drive with 30G free space: With 100 files on board, performance seems very similar to the Power Mac G5 above. This isn't my machine so I can only test on it occasionally. - Running on a PowerBook G4 1.67Ghz with 1.5G RAM and an 80Gbyte drive with 20Gbyte free space: Imported 250 DNG files by reference, took about 10 minutes. Total in the Library now comes to about 380 files. Performance with the trackpad is a little unresponsive ... I find it easier and more precise to use the arrow keys in the Develop module. No particular slowdowns, but you can definitely see that the single processor/older chip configuration leaves a bit to be desired. The same differential in performance is easily visible when running Photoshop CS2+Bridge +Camera Raw.
