    General performance question

    Hello,

    I have a page containing 7 iframes. Each document is created through
    PHP, 8 in total. I had performance issues which I could solve through
    Wincachegrind - now according to it, each of the 8 takes only about
    20ms, i.e. the whole page should be loaded in less 0.1 seconds. In
    fact, it takes more than 5 seconds to load. The HTML is pretty simple.
    I wonder how I can detect the bottleneck reason? Any hints? Is there
    any general communication settings, in php.ini or I don't know, e.g.
    about parallel connections or so, or things to take into account to
    load an iframed page more quickly?

    Thanx in advance!
    Daniel

      Are you using PHP sessions? If so, each page (or iframe) requested
      will open the session, lock it, execute, write the session back, then
      release the lock. While that data is locked the other pages (iframes)
      will wait -- which may be what you're experiencing.

              Do those 7 iframes do something that can't be accomplished in the main
              page? Do you need session data in all of them?

                  Not really... The best way to deal with this problem is to get rid of
                  iframes altogether. When the main page loads, it triggers the loading
                  of 7 iframes, each of which is a page in its own right. So every time
                  the main page loads, the server has to process eight HTTP requests.
                  If each of this pages is database-driven, you also end up with eight
                  database connections.

                  Alternatively, if some or all of the iframes are static or not
                  frequently updated, you could cache them...
