Yesterday evening I waited about 1.5 minutes (yes !) to have the new SQL quiz page displayed ... For all this time, all that I could see was the upper part of the quiz page, with the table definition and the INSERT statements only ... but not the quiz itself and of course not the choices.
Sometimes the complaints have to do with rendering the images for the quiz. Sometimes the problems appear on virtually every page of the site.
Is this a problem for you? Please post comments regarding any sorts of performance issues you have. We will also create a poll for this question.
