Dear Doug,
Thanks for the information. If you are not conducting any data transfers that is, uploads or downloads limewire uses very little of your connection about 23Kbps or 3KB. It would help if you conducted some speed test while not running anything else and posting your results here. You can use the following url:

This will provide the bet measure of your transfer capabilities. As for the issue with exactly 11 results showing up for most results -- I noticed that too and I'm not sure why that happens.
Regarding your upgrade to the pro version I never buy the pro version for more performance but rather just to support the developers. The pro version does give you a little better reach in to the network by connecting you to a few more ultrapeers.
Problems with download speeds have been talked about all over the forum and extensively in this thread.
Look through the thread and follow the conversations that deal with download speeds.
Hope this helps.
