Hi Viktor,

Based on what I've read on this list, I expect that you will see
substantial performance and reliability improvements if you switch
from file:// access over a Windows network share to svn:// protocol.
The svnserve network server is very easy to setup, and is highly
optimized for remote access.

Unfortunately, I don't think it is ever safe to access Subversion
repositories over a Windows network share. Many users have reported
reliability problems in this scenario. The FSFS backend for Subversion
is designed to be accessed safely over NFS; this same guarantee does
not apply to Windows network shares which have very different
semantics, and have never been officially tested with Subversion.

See http://svn.haxx.se/users/archive-2007-03/0628.shtml for an example
of a Subversion repository which experienced reliability problems due
to being accessed over a Windows network share.

Cheers,

David
