In multiplexed mode (the default), the receive buffers are of fixed size and are probably not big enough to accomodate fast links with high latencies. I'd suggest trying passive mode with "-P -" on the cvsup command line. This may solve your problem, or at least help. If it doesn't, then it might also be necessary to hack the code to increase the socket buffer sizes. Unfortunately, that would have to be done on the server side as well. John -- John Polstra John D.
