You are definitely right!

I tried a similar szenario as Eric did.

Copied /usr/X11R6/shared to /tmp/test/shared

du -hs shows around 58M
There are 2149 files.

time darcs record -am "test"
darcs record -am "i"  61.12s user 4.98s system 84% cpu 1:17.86 total


darcs record -m "test1" and answering 'a' gives:
darcs record -m "i"  338.87s user 5.84s system 88% cpu 6:28.06 total

This is FreeBSD 5.3 and darcs 1.0.1rc3
