Powerbook G4 500Mhz
512Mb RAM
OS 10.2.2
Limewire 2.8.0

Limewire:
peaks at 90% CPU on startup
10%-20% CPU when running idle with stable connections
peaks of 40%-70% CPU when searching
More or less constant at 10% memory (50Mb)

Window Manager peaks appear to be unrelated to Limewire. Mine operates at 2%-7% CPU normally - with or without Limewire running. Running the mouse pointer along the Dock with magnification on, for example, will cause the WM to peak at 60% CPU for a second or so. Many other normal operations (like window or application swapping) will cause similar peaks.

I tried starting Limewire from the Terminal and got similar CPU percentages ('com.limegroup.gnutel' instead of 'Limewire' in the Process Viewer).

I have successfully downloaded and uploaded files with no specific problems apart from the 'Could Not Move To Library' error which occured twice with one specific file (illegal characters?).
