Wrong mailing list - this is a Subversion question. TortoiseSVN just
uses the SVN client libraries so it has no control over that side of it.

The real bottleneck does indeed seem to be the server, or at least the
WAN connection to it - the tortoisesvn repository is also painfully slow
sometimes. I use svn:// protocol on my server at work and transactions
over broadband from home are almost as responsive as over the LAN in the
office. Going transatlantic might be slower of course. SVN is currently
developing a new http layer based on Serf instead of Neon. That may help
- maybe ...
