Caching and headers

[quote author="Arjen van Bochoven" date="1226507284"]As for the expiration time: I was happy to get rid of the preg_match() and trade it for unserialize() which I assume is faster and less memory consuming than the regex engine. Maybe someone can confirm this?[/quote]

okay I've done some (basic) benchmarking and you're right
I've expected the regexp to be faster than the unserialize operation
but it's the other way round.

the code in the wiki takes about ~0.00018 seconds to display the cached
content "my" code takes ~0.00026.

on caching the wiki-code is still faster, but the difference is not that big ~0.00027 to ~0.00029s.


whats more important? speed or less code-redundancy :-S

EDIT:

I've done some further benchmarking for the ones wich are intrested.

the regexp part for stripping out the timestamp IS faster than unserializing the cache file.
but because we have to unserialze the cached data either way...
the "advantage" of the regexp-variant would be the faster detection of expired cache-files.
