FYI I did a bunch of tests with various browsers and found that the Ad Blocker in Firefox sometimes fights with the Google ads on CT.  Even though you don't see those as a member there are still processes running in the background on CT when you query the database (entering wine, consuming wine, etc. etc.).  Try turning your Ad Blocker off and hit CT a few times and it seems to work it out then turn your Ad Blocker back on.

I've posted with Eric a few times that I was seeing slowdowns as much as 20-30 seconds to load and display a query but everything looks fine from the CT end.  The suggestion above is one of the only things that I've found that works.
