Git Question

Git/Bash is extremely slow in Windows 7 x64

I've been using Git on both Windows and Ubuntu during the development of a small project, frequently flipping back and forth between the two. The issue I'm having is that Git/Bash consistently become slow. When I say slow, I mean that running

takes anywhere from 8-25 seconds, running
commands take from 5-20 seconds, and
can take up to 30 seconds sometimes. Needless to say, this is not fun, not to mention unproductive. I know Git is slower on Windows, but this is ridiculous.

The one solution which has worked--temporarily--for me has been to disable my network connection (as suggested in this answer), start git, and then reconnect. Sometimes it continues to run quickly for days after doing that, but the performance always degrades eventually. I've trawled through the msysgit discussion group, SO, msysgit issue list, etc. on and off for weeks, but I haven't been able to turn up solutions which work.

So far, I've tried:

  • Adding git & project folders to virus scanner's exclusion list

  • Disabling my virus scanner completely (Kaspersky IS 2011)

  • Ensuring that Outlook is not running (Outlook 2007)

  • Shutting down all other applications

  • Running git as administrator

  • Disabling network connection, starting git, and keeping connection disabled

  • Disabling network connection, starting git, re-enabling connection (works only occasionally)

  • Running git gc

  • And combinations of the above

I did read that a couple people had success disabling bash completion, but ideally I'd like to keep that active. The version of msysgit is & the OS is Windows 7 x64. Running the same things on Linux is, predictably, lightning fast. I would use Linux exclusively, but I need to run stuff in Windows, too (certain apps, testing, etc.).

Has anyone encountered a similar issue? If so, what was the underlying problem and what was the solution (if any)?

Edit: This extends beyond just the git repositories, but just for reference, the repos I've been using git with have been pretty small: ~4-50 files max.


It appears that completely uninstalling Git, restarting (the classic Windows cure), and reinstalling Git was the cure. I also wiped out all bash config files which were left over (they were manually created). Everything is fast again.

If for some reason reinstalling isn't possible (or desirable), then I would definitely try changing the PS1 variable referenced in Chris Dolan's answer; it resulted in significant speedups in certain operations.
