@sba: I know it's the hard disk that slows down my system and i've cursed toshiba atleast 150 times (

) for making such an awesome laptop and then crippling it with a slower hdd. Anyway, I am sure it's Azureus coz my system runs smoother @ 3-4 Mbytes/s downloads using i2hub compared to 300-500 Kbytes/s downloads using Azureus.
I am running Azureus 2.3.0.4 and JRE build 1.5.0_04-b05, most prolly the latest ones.
By the way, sometimes i connect to more than 150 peers for a single torrent. System slowdown due to that many connections can be attributed to a slower processor but i believe Pentium M 1.7GHz w/2MB cache is a pretty powerful cpu so that doesn't make any sense.
