Thanks for the feedback! Again, I'm really glad to have an end-user on this list reminding the developers of what he wants. Let's prioritize faster uploads and downloads for tahoe-1.4. This is the ticket describing what we already know about it: http://allmydata.org/trac/tahoe/ticket/392 # pipeline upload segments to make upload faster It would actually be a reasonable task for a newcomer to tackle. To real solve it in the best possible way is equivalent to reimplementing TCP on top of foolscap messages, or else switching from foolscap to HTTP for storage protocol, but to do some reasonable hack that makes it, let's say "twice as fast", for typical situations, should be quite doable. See these graphs of how throughput has *dropped* dramatically as we've changed Tahoe to make it better along other dimensions: http://allmydata.org/tahoe-figleaf-graph/hanford.allmydata.com- tahoe_speedstats_rate.html In fact, that graph reminds me of an even *easier* hack, just set the segment size back to a few MiB instead of its currently value of 128 KiB, and see if that significantly improves performance from Andrej's perspective!
