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?)
