Quite. GPRS has a round-trip time of about a seconds. This immediately translate to every remote svn operation (even 'svn ls') taking fifteen seconds. It was thirty before my sysadmin enabled 'Connection: keepalive' on the server. Anyway, this indicates that svn regularly does about roundtrips on remote operations. > Could > that change you are talking about be meant to address these redundant > repeated requests? They are.

So I wonder if could be missing anything. It *may* be another opportunity to bash the maturity of libsvn. :-) I assume the aforementioned protocol change does not just mean eliminating these redundancies. > Given than a typical gzip encoding can compress text data about 5 times, > it seemed to me there is a great opportunity to make SubVersion HTTP > server accesses much faster, but that opportunity is not being addressed > because SubVersion HTTP servers do not compress responses. Again I maybe > missing something here. I use ssh port forwarding for svn http:// access anyway, and that can take care of the compression, even of the headers.
