Vuze is a memory leak pig, along with Internet Explorer using multi-tab configuration. Various apps (granted some are utilizing FLASH) leak memory and are CPU / Reource hogs. I constantly see 0 memory left and CPU scales doing acrobatics to keep up..
Maybe I'm jsut lazy in keeping 4gb and not upgrading, but gimmie a break-- There is no excuse for lazy programing. 4 ie tabs open and vuze running a few torrents shouldn't bring a 4 year old system to it's knees.
