oprofile will tell you.

I don't see why it would spend a lot of time in the kernel, unless it's 
the SVN part that does a ton of reads or something. git should have almost 
no kernel footprint apart from the individual objects creation/reading, so 
once it's repacked, I generally see very little system time.

What does top say? (Ie can you see _which_ process spends time in the 
kernel?)
