    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_sch ema.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.

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

                                      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.
                                      Google around for "Premature Optimization" and see what you can find.
                                      I'll have a look :)
