The fact that curl PUT is faster is because the svn client first stores
the delta to a temporary file, and only then sends it to the server
(and there's also compression and checksumming involved). Curl streams
the data to the server, and the server can immediately start processing
the incoming data.
If the svn client would be streaming data as well, it would make the server
and the client process data simultaneously and also avoid the overhead
associated with writing the temporary file to disk. Perhaps, that would
make the difference much less visible.
There is a sketch of the solution available in:
but I wasn't able to finish the work on it.
