I have run darcs-benchmark using darcs 1.0.9 and am now able to
compare:
darcs 1.0.9 on version 1 repository
darcs 2.2.pre2 on version 1 repository
darcs 2.2.pre2 on version 2 repository
On the (rather large) cap repository, darcs22pre2 used about a third
more memory and took more than three times as long to get.
For some reason the check and repair benchmarks failed for darcs109,
but darcs22pre2 took more time and used more memory for these on the
version 2 repository than on the version 1 repository. Likewise for
repair.
Pulls are somewhat similar when using a version 1 repository, but use
more than six times as much memory and take about twice as long on the
version 2 repository.

On the (somewhat smaller) systems repository, getting used less than a
tenth as much memory on the version 2 repository, but took five times
as long.
It took less time to check and to repair using darcs22pre2, but used
two to three times as much memory as darcs109.
Pulling fewer patches on darcs109 was faster, but pulling more patches
was faster using darcs22pre2. Memory usage was similar for all of
the 'pull' benchmarks.

I am encouraged that darcs22pre2 on a version 2 repository is
performing so much better than earlier versions of darcs2. I am still
concerned that it uses so much more memory for check and repair, and
sometimes pull, and that it is so much slower for pulls and gets.
