Actually we're not LW just a forum. If I can make a suggestion just to try: go to LW menu Tools-Options-Speed & untick OOB Searching & see if this makes any difference. It might not & it's purely a 'stab in the dark' from my point of view. But heh why not try it. If it improves it, it improves it, but then maybe not.
Again, make sure you have as high as possible quality stars & preferably more than one source. You could even go to your Tools-Options-Searching-Quality & select show only 3 & 4 stars or just 4 stars. This will lessen the chance of you connecting to a poor connector source that's within a group of sources.
