Discuss Joomla! 3.8.0

[itoctopus]

There are now quite a few complaints that Joomla 3.8 is (much) slower than Joomla 3.7.5. Not sure if this caused by a possible increased number of requests that Joomla 3.8 makes to the web server causing a firewall throttling, or if this is caused by some slow queries. After reading the last forum post on this subject, I am inclined to think it is probably the former.

Ole Bang Ottosen just replied through twitter about the performance issue here: https://twitter.com/ot2sen/status/912402329336451073 - it seems that the "onContentPrepare" event is fired twice. See: https://github.com/joomla/joomla-cms/pull/18066 . Thank you for the Joomla team for immediately investigating and confirming the issue.

Just want to say "THANK YOU!!!" to preceptm for the SQL solution. I tried the various "turn off extensions via phpAdmin" fixes and still had a white screen admin. However, after running the SQL commands you provided, my backend is back! Thank you so much!

That worked!

Thank you so much. My xxxxx=Jos and this code worked perfectly.
