php object performance

Hello there!

I've tried to gather some infos about php object performance.
I got started developing an app using php object and have the worst
requests time I ever seen.
I mean, once all my classes uploaded on a host, I call index.php to
get classes instanciations and it could take 55sec to generate the
first response and about 1 or 2 sec for the following calls..
...and I'm scared about those latencies.^^
I only have less than 10 classes with inheritance and some calls to
SQL server but it sounds that I don't follow some basic rules.. ^^
Hm... how do I have to consider php object performance ? What searches
have I to make ??
I'm getting lost.. I don't know what and where to look after.. ^^

any idea ?

Thanks a lot :)

I highly doubt that "php objects" are to blame for your problems --
more likely something in the code itself. Even more likely something
to do with the database. Get a profiler to figure out where the
problem is, or place some strategic echo's throughout your code and
run some timing tests.

a profiler?? I've heard a little about it.. ok, I give a try.. and let
you know, if necessary.. thanks ZeldorBlat

Are you using autoloading?

No, I gave up knowing that this magic function is costly.. I prefer
require_once() the right class when needed.. :)

How do you know it's costly? I've never had a problem with it...

Indeed, autoloading is not the same as preloading. It should have very
little effect on resources.

Really? actually, I read this hint on some websites.. that may be
false, however :)
well, concerning my issue. the following request:
SELECT COUNT(*) AS nbre FROM information_schema.tables WHERE
`table_type` = 'BASE TABLE'
...is responsible for such a latency. It uses predefined tables in
mySQL engine... I switched to an other board (comp...mysql) to discuss
it.. :)

Don't trust everything the internet tells you. Try something first,
then optimize if you run into problems. Often you'll find that the
problem has little to do with what you thought it did and everything
to do with what you didn't think it did (as this thread is evidence
of).

Google around for "Premature Optimization" and see what you can find.

Sure :).. usually, I run into empirical tests before taking any
decisions. And I am aware that premature optimization could lead into
troubles.. but how to start optimizing after conception without having
to remove/modify essential pieces of code due to optimizations ? I
think this is a debate that deserves its own thread, I'm off topic :).
Interesting debate, though.

I'll have a look :)


Thanks ZeldorBlat.
