It would be good if you could help us reproduce this (and maybe open
a ticket).

Here's what I get on the darcs darcs repo with Darcs 2.3.1, the current
beta and an unstable version with some recent work.

% darcs-benchmark run darcs-2.3.1 darcs-2.3.98.2 darcs-2.3.99.1p1 / darcs --only annotate

+----------++--------------------+-----------------------+-------------------------+
|          || darcs-2.3.1        | darcs-2.3.98.2        | darcs-2.3.99.1p1        |
+==========++====================+=======================+=========================+
| annotate ||       18.1s 181.0M |          16.5s 181.0M |            16.6s 181.0M |
+----------++--------------------+-----------------------+-------------------------+

For the interested, darcs-benchmark is just a cabal install away.  Setting it
up for your favourite repo is pretty painless.

Either just call it "repo.whatever", or write a config file "config.whatever"
in the JSON format I mentioned earlier and attached again for convenience.
