   Really?  That's very surprising.  For me it's about 5 seconds to switch
   between some emacs branches, with a cold FS cache (once stuff is in the
   filesystem cache, switching is essentially instanteous).

Maybe is has to do with the hardware then; my /home is mounted
onto a SDHC card as my current laptop does not have a valid
internal HDD.

Here are the results of consecutive git branch/git checkout:

xma@localhost> git branch                                                                                     ~/usr/src/GITed/emacs
* master
  rmail-mbox
xma@localhost> time git checkout rmail-mbox                                                                   ~/usr/src/GITed/emacs
Switched to branch "rmail-mbox"
git checkout rmail-mbox  5.97s user 1.04s system 6% cpu 1:41.16 total
xma@localhost> git branch                                                                                     ~/usr/src/GITed/emacs
  master
* rmail-mbox
xma@localhost> time git checkout master                                                                       ~/usr/src/GITed/emacs
Switched to branch "master"
git checkout master  5.16s user 0.88s system 8% cpu 1:07.25 total

As you can see, the results are really bad but I do not
switch between branch so often.
   
   Are you per-chance using windows?

Are you joking ? :) I am using a real GNU/linux system, more
precisely, it is a Slackware 12.0 GNU/linux system.
