But it comes from cache after the first hit.

If the action itself isn't cachable, it does not mean that the rest 
cannot be cached.

Did you measure the overhead here? It was pretty low during my tests.

Same here. Instantiating classes is pretty cheap.

Will be cached after first hit.

Well, if you need to call an Exbase action via Ajax, then this is of 
course a price you have to pay.

Same here.

I know :)

Well, yes of course.

True. If you need to optimize that much or have a simple case where you 
do not need anything but a DB connection or a simple FE user, eID is the 
way to go; sure!

But *if* you need a page (TSFE) or even TypoScript, bootstrapping all 
this in your eID script is hard to get right. You end up with C&P almost 
all of the code in TSFE, which at best slows down your request to a 
regular page request level which never will be cached (so it is slow for 
every request), at worst you end up with broken code that will also 
break regular requests (as wrong things could get cached for your page).


Summary:
* Easy code with no dependencies: eID
* "Normal" code with dependencies to TypoScript: typoscript_rendering[1]

:)


Kind regards,
Helmut
