I don't think the hard drive matters much at all; the CPU is pegged the
whole time. I'm not fully packed, but almost so. I suspect it is a
combination of:
1. I compile git with "-g" and no optimizations to make debugging
easier.
2. My system sucks. It is a 1.8GHz dual Athlon from around 2003.
fast-export should be pretty memory intensive, which I'm sure is
saturating my totally rocking 266MHz FSB.
Just for fun, I tried:
- fully repacking; no change
- compiling with -O2; shaved off about 2s. Not too surprising;
previous profiling has shown that git spends a lot of time in zlib,
and I am dynamically linking against an optimized version.
So I think it is mainly (2) above, assuming your machine sucks a lot
less than mine.
