Be prepared for version 2.3, in beta testing right now.
Experimenting on build #147 i finally found a way to make speed tests over the internet, and worked like 4 hours on speed optimization.
the optimization concerns high latency (ping) connections but with good speed, like 1mbps (don't know about slower ones).
Foggy and me tested it right now over a 420ms ping connection (italy-australia), with 916kbps (114KB/s at its best).
speed for versoin 2.2a (current official version): 18KB/s
speed for version 2.3 (build #147): 80-90KB/sThat's just great, and i can't wait for it to be published.
Information for beta testers: speed observed for build #146 was 30KB/s
