Slow file deletion on Windows 7 RTM

The picture below says it all:



Of course, it didn't actually take 23 hours. It actually took about 45 minutes - that's around 13 items per second. More than half of which was taken up by calculating how long it was going to take (estimating the quality of the calculation is left to the reader).

Now I understand the need for transactional semantics during a delete, the necessity of shared filed locking, and the possibility of file system watchers getting involved in their own idiosyncratic ways.

But 13 items per second? On a 10,000 RPM drive? Seriously, guys.

Try to disable Recycle Bin on you drive, and also turn off System Protection (esp. "restore previous versions of files") on your drive.
