[TYPO3-performance] Backend Performance TYPO3 4.3 - Strange Behavior

[Raphael Heilmann]

Hi Susanne,

Do you use more than one page (sys_) language? Try creating a MySQL index in
tt_content table over the following fields:
l18n_parent
sys_language_uid

We had the same or a similar issue after upgrading to TYPO3 4.3, when
accessing the Web>Page module for pages with lots of content elements on it.
Creating the index solved the problem for us. 


Best regards

Raphael Heilmann

horrible task anyway.

You could do this to examine SQL:
go to db_layout.php and add this:
$GLOBALS['TYPO3_DB']->explainOutput = 1;

use cc_debug for 4.3 and see what happens in page module.

Good luck!
