I am using Windows XP Professional, Intel P4 2.8 GHz CPU and 1GB of DDR RAM. When I download 3 torrents at the same time, my CPU usage sky rocket to 60% which prevents me from doing anything useful except maybe surf the web. I would like to know if there is anything that I can do to improve the performance? If I increase my disk cache size, will that help? With previous versions, I was able to open 5+ torrents without noticing any significant effect of system slowdown.
I’d suggest you revert to the last stable version, and avoid upgrading until a later stable release is announced.
