et voila:

Are you 100% sure the CPU problem is unrelated to hashing? Does it happen if you're disconnected from the network?

Thanks,

connected without downloads/uploads 20-25% of processor and disconnected is about the same. Wow! If I unshare, cpu usage stays the same.
5 mins passed...
I totally uninstalled LimeWire components of my home folder, and reinstalled it from a new download, still 25% cpu usage disconnected and no sharing. HEH!

What version of MacOS are you running? What version of Java?

Try making sure that Tools->Options->Connection->"Connect on startup" is unchecked and set your keep-alive to 0. Now quit LimeWire and restart. Do not hit "connect" or adjust the keep-alive. Is the CPU still high? Double check that you are not connected by looking at the connections tab.

Thanks,

Mac os X.2 clean install french language both Os and limewire. so java 1.3.1.

Been there done that, CPU still over 20% with limewire 2.6.1 even when I modify ads.props to not have ads! Also since limewire 2.5.x (at least on mac os X.2) sometimes the start setup pops up at random when opening limewire and I have to re-enter all my config. Hint: Is your InstallAnywhere up to date for this OS?? Have you ran lime on the new operating system? Is your .plist (preferences) effective? It looks as a java loop process, but what do I know about that? Nothing.

Bonne chance Lime team!
