Hello again,

I built GHC 6.8.3 from source (a plain old tarball, not a Debian
package). Then, using that, I compiled darcs (the version right out
of the repo at darcs.net).
This works much better!!!
The same simple darcs operations that I was complaining about
previously now run on the order of 0.6 seconds. (Previously they were
taking nearly 10 seconds.) This is quite acceptable.
By the way, I couldn't help noticing that it's still a bit slower than
the (very impressive) 0.1 seconds I used to get for a "darcs w". It
turns out that if I repeat the exact same experiment, except without
specifying --darcs-2 on the "darcs init" command, then I do get back
to the even faster 0.1 second range (even using the darcs2 executable
that I compiled).
It appears that the old repo format works a little faster than the
new, in my case. Does that make sense?
Anyway, thanks to you all for the hints. I'm content now.
Cheers,
