Performance with high network latency

[Christopher Key <cj...@cam.ac.uk>]

Hello,

Apologies if this has already been covered.  I'm using tortoisesvn with an 
SVN repository via http over the internet.  Whilst the transfer of files 
during an update following a switch is perfectly fast, ~50kb/s, the initial 
'handshake' that occurs is excruciatingly slow, running at something of the 
order of 100 bytes per second and often stalling altogether.

Ethereal shows the traffic as repeated 'PROPFIND' requests, with about a 
seconds delay between request and response.  The delay appears to be 
somewhere in the connection between me and the server.

It seems to me that it is somewhat suboptimal to be sending out <1kb packets 
every second when the link is capable of sustaining ~50kb/s.  Might it be 
desirable to adapt the client slightly so that multiple requests can be sent 
with each HTTP request.  Even a reasonable network latency, say 50ms, means 
that only 20 requests can be handled per second, possibly still as issue for 
repositories with large numbers of files
