bzr performance (blitz speed on GNU/Linux compared to M$)

[dhruva]

Hello,
 I have been using bzr on the emacs repository on M$ platform for quite sometime. I decided to start using bzr on GNU/linux for my official work (bzrp4 is what I need). I must say the performance of bzr on GNU/Linux is far superior than on M$. I am no expert to figure out which portions of bzr are heavily OS layer dependent. It may be worth an exercise to find out portions of bzr which depend a lot on the OS provided services like file IO or network layer or ...
 To make sure I have a similar setup, I disabled on access scanning by anti-virus on folders containing my bzr repositories. I did see a major performance improvement once I did that. I am posting this here so that when someone else sees slow performance, they could look at what AV is doing when bzr is working. If bzr makes lot of file open->read/write->close, that triggers the AV. Maybe, fewer open with multiple writes is better. Not sure if this is relevant in the context of bzr.
