Hi all,
With the network plugged in, git-commit takes 8 seconds.
When I unplug the network, commit is instant...

I confirmed this with a fresh test directory, just adding an extra line to the file "test" for each commit:

> git init
Initialized empty Git repository in /home/user/gitexpt/.git/
> vi test
> git add *
> date; git commit -a -m "add minor change"; date
Mon Nov  3 00:31:02 EST 2008
Created commit 9b845a2: add minor change
 1 files changed, 2 insertions(+), 0 deletions(-)
Mon Nov  3 00:31:10 EST 2008
> date; git commit -a -m "add test, without network"; date
Mon Nov  3 00:46:00 EST 2008
Created commit dd02a69: add test, without network
 1 files changed, 3 insertions(+), 0 deletions(-)
Mon Nov  3 00:46:00 EST 2008
> git --version
git version 1.5.6.3

Anyone know why is git-commit so slow? Or if there I can anything to change this?

I'd assumed the slowness was normal, since I'm new to version control. I've googled and searched mailing lists, but haven't found this. Could be just my installation (or others make the same assumption?)

Many thanks for any help... I'm going a little crazy here.

Configure your user.email (and user.name), see man git-config. If the email is not set, Git tries to figure out your hostname, which depending on DNS misconfigurations can apparently cause such delays.

Many thanks for the explanation, and it's now instant.
To ~/.gitconfig, I added:
[user]
  email = myemail@address.com

I'd like to point out that in addition to making git not try to figure out your hostname, you may well want to try to fix your setup so that it doesn't take that long in the first place.

In fact, you might use "git commit" (or "git var -l" which probably shows the same 8-second thing more easily without needing anything else) as a way to debug what it is that takes too long.

Because even though adding your email to yout .gitconfig file is the right solution _anyway_ (because the git guess is rather more flaky than you just telling it what host to use), I bet there are other programs that will have the same 8-second delay, and you are better off trying to just fix your DNS problem.
