Hi, One month since I have a Vista 64bit installed on my PC and still couldn't find suitable torrent client for it. I have tried uTorrent, BitComet and Azureus. Non of them doesn't preform well for me on the new 64bit platform. I have made some basic optimization for these programs and used few tweaks too, but it doesn't help much. With uTorrent I have near 100% RAM utilization (2GB), a huge page file and intensive disk activity. BitComet constantly loads my C2D CPU on 60-70% and in time it progressively utilizes all of the memory too. Azureus loads CPU as badly as BitComet does, consuming less memory. When a single torrent is loaded on these programs and the download speed exceeds 2 GB -all other opened programs are notably slowed down. With download speed reaches 5GB - everything except the download client freezes. It is impossible to listen music when downloading, because frequently CUP utilization reaches 100% for millisecond and then drops down causing this way an audible noise. That noise is present even with real time priority for the players process. So is there another program to be used as a torrent client on Vista 64bit free from such weaknesses? I will be glad to hear some advice. Thanks.
