I really question removing rsync before HTTP pulls become more effecient. I did a complete pull of cogito from kernel.org, and http took over 50 minutes to pull everything, while rsync was done in just over 1 minute. I dared not even try to pull the full kernel at that speed. I suspect that part of the problem is that the pull methods are doing a depth first search, so we can't request the next object until the current object is fully received and parsed. Changing to a breadth first search would allow multiple requests in flight and asynchronous processing which should speed things up. I am exploring using the curl_multi_* functions to do this, but this will require changes to common code in pull.c. -- Brian Gerst
