I do not doubt it is important to some people but we cannot hold the
release forever. If no one is going to stand up and test it then they
are going to have to keep their fingers crossed that it will be OK. I
did provide Windows binaries for people and TortoiseSVN has been
providing nightlies. No one asked about any other OS. I am guessing
for Linux at least we would have had someone that could have tarred up
a build or something.

So it sounds like you want to test a server with repos on NFS? I do
not think there is any reason to think 1.7 would have made that worse
and hopefully with the caching it made it better. We mainly need
people to test that normally locate their WC on NFS. That is where
there might be concern over performance. That said, given all the
optimization we have already done it is hard to know what more we can
do. If performance is bad with NFS then it will likely be a symptom
of SQLite on NFS and we are not going to be able to do much about
