Re: Subversion/Eclipse Performance on Windows

I've tried adjusting the NTFS options, disabling indexing, and turning off
real-time virus scanning. Of those, the only one that had a noticeable
speed improvement was turning off the virus scanning, which improved
performance by about 25% on heavily I/O-intensive tasks such as svn

But even with the improvements due to these configuration changes, there was
still a huge difference between Windows and either Linux or MacOS in the svn
checkout and svn switch tasks. The exact reason remains a mystery.
