  The PHP Scalability Myth

Performance: time to finalize an user action


Scalable: time to finalize thousands of concurrent user actions not very different than serving one.


PHP-JSP : similar performance.


JSP only performs better than JSP-J2EE, obvious.


But:
JSP only NOT SCALE.
PHP only NOT SCALE.


JSP-J2EE scale => thanks to distributed and parallel programming.


Please rewrite the article.

    What is your definition of J2EE, because if your definition of J2EE includes a JSP/POJO configuration then you have a logical three tier architecture which is exactly the same as PHP. How is it then that JSP-J2EE scale and PHP not scale?

    Without more concise information I cannot 'rewrite article'. I appreciate the please though.

    In other words, with a thousand users accessing a single server, PHP may work as well as Java.

    For a million users, 10 servers using J2EE architecture can perform well.

    What do you do with PHP?

    I think the previous commenter is observing that
    *real* scalability is architectural, and explicitly
    provides for distribution and parallelization.

    That's apt, of course. Without providing details
    I can't afford (in time) just now, I'll counter-assert
    that, while Java certainly has plenty of distribution
    stories told about it, PHP and other scripting alternatives
    should feel no shame. I applaud author Jack Herrington
    for at least opening the debate with a proper focus on architecture.
    His is an article that needed to be written, and I
    hope it will be widely read.

    scalability is achieved either by having a "read-only" application, which can be easily deployed on multiple servers, or by having a way to distribute the changes on multiple copies of the database. It has a lot more to do with _how_ you write the application rather than which particular language, libraries or platform you choose.
