Hmm.. that makes sense that WebDAV would be slower. 2X slower is a pretty
stiff penalty though.
I have not tried the Serf client library. I didn't even know that was an
option until I read your post. From my research on the Serf web site and
the "Serf and Subversion" thread on dev@svn, it looks like Serf support made
it in to svn 1.4.3. Is Serf 0.1.0 what I should be linking with? Or do I
need the latest development version of Serf?
The libsvn_ra_serf/README states "Basic authentication" is supported. Not
sure if that includes more complicated providers like LDAP. Does anyone has
experience with this?
Has anyone done a real-world performance comparison with Serf vs. Neon?
