Somebody else was complaining about the identical thing just days ago.

1. Go to LW's menu Tools>Options>Speed & tick Disable UltrapeerPeer capabilities. And press the Apply button.

2. Tools>Options>Basic & reduce the Upload speed slider back to under 80%. If you find it's not enough then reduce it further.

3. After opening LW, don't do anything with it for at least 15 mins. Depending on how many incomplete & shared files you have, LW takes some time to settle down & during this time can be very cpu & bandwidth demanding. I often don't do anything but turn LW on; eg: http://www.gnutellaforums.com/showth...028#post116028

4. Don't use the Resume button on too many (if any files) in order to continue them. This can make LW work overtime & use up large bandwidth & lots of cpu processing power. Manual searches are much more effective anyway.

5. Close any LW windows you'e not using at that time, eg: Connections & Monitor windows.

6. Set your downlds for auto-clear (Options>Downlds & tick Auto-clear option & press Apply button.

7. Get rid of any search results that are older than a few hours. Search results can go stale after a while.

All these things will help to reduce LW's burdon on both your computer & your connection.
