Yes, 29 hours should be about right for you to finish five WU's!! What else do you have running on that system? Is there anything running in the background that you can close? Are you running the Command Line client or the Windows GUI client? If you are running the GUI, do you have it set to automatically blank the screen? If not, you definitely should! In the Windows Task Manager (I'm assuming you're running Win2K) does the SETI client show as using about 97-99% of the CPU? If not, what else is using CPU time?
