I've noticed that the html editor appears with a noticeable delay (after the whole page has loaded), sometimes even longer than 10 seconds. The delay is different on different moodle sites, but even on the same site the length of the delay may vary considerably. Does anyone know what might be causing this? Is it a server performance issue? If so, which of the server parameters influences this?
This did not happen in Moodle 1.9, but is quite common on quite a few Moodle 2.x. site that I have access to.
