I don't know much about Windows (that looks like a Unix time?) but
your timings appear to show almost no CPU usage in the client. I
guess the client is spending all it's time waiting for IO, which means
the problem is either the server or the network. I suspect the server
is your bottleneck, it takes quite a bit of CPU to decode the svndiff
received from the client and then encode it for the repository. (I'm
a bit surprised that the client can encode a 1GB file using only
0.031s of CPU.)
