Now we analyzed our problem and have noticed, that when someone uses the IE11 to access a wiki, and this wiki has a embedded video, there are starting a lot of requests for this file (*.mp4). With the Chrome/FF they're about 4-5 less mysql connection started.
Active SQL connections when accessing a wiki:
- Chrome/FF: ~5-7
- IE11: ~25
In the apache logs i've seen that the called files are the draftfile.php and the pluginfile.php. Normally with the Chrome/FF they're only opened 1-2 times. With the IE instead there are > 30 requests...
Have someone other the same problems?
