[TYPO3-dev] Typo3 Performance

[Nicolas Cohen]

I would suggest documentation has at least 2 levels of depth in the 
optimization, considering difficulty of the task and degree in which it 
improves performance.

eAccelerator required to have phpize installed and superuser shell 
access.it gave a lot of improvement. i would probably mention it in the 
first level of recommendations.

fiddling with http and mysql config files didn't show much improvement 
for me and is completely subjective to the set up of the machine. It 
could easily make things worse if one touched that stuff without 
knowledge. i understand that with proper knowledge, one could get some 
performance boost, but i am not sure how much

a file cache gives a lot of improvement, specially for non interactive 
pages. and interactive pages gain performance from the new free 
resources. Installing the static file cache extension is pretty 
straightforward (the hardest thing is editing the htaccess file)

installing apache's proxy cache is harder though it seems like a better 
solution

usage of the ab tool for performance measuring should be mentioned and 
any good way to know if extensions are not cachable too...

my two cents
