[TYPO3-dev] Speeded up TYPO3 by 500% :)

[Bernhard Kraft]

Hello boys and girls,


I tried it already in 5 different variants during the last year but this
time I think I got it ...

Have a look at the following ab2 (apache benchmark) outputs:

You see that the "Requests per second" is about 500% higher than normal.


I achieved this by creating a "stripped down" (no included files) index.php
which checks if there is a cache-file for the current requested page. if it finds
one it checks if it's still not expired and if it's valid it simply outputs and
exits.

It is not compatible with any FE-User login currently and if you view the pages
as logged in BE-User you will also get no "quick-index".

But for simple sites without any FE-Users you get a lot of speed improvement.



A T3X for download is here:
http://think-open.org/kraftb/index/T3X_kb_quickindex-0_0_0.t3x



Currently it will only run under UNIX cause I use "rm -rf" to quickly remove the cache
directories when the "clear cache" button is hit in the BE (see class.tx_kbquickindex_tcemain.php)


See "README" file in extension directory for more information.



I would be glad if somebody having a running PHP-accelerator setup could test it on his machine ...


greets,
Bernhard
