With a local filesystems it is usable, but I need to test it at work
with my NFS-mounted home directory.
My general perception is that many things are quicker, but operations I
would expect to be instant (and were very quick with darcs 1), like
pulling/unpulling 1 patch in a GHC repo, are taking several seconds with
hashed repos and darcs 2. I've tried optimize --reorder, to no avail.
This is resulting in an overall impression of sluggishness, which is
