    ASP, CGI and PHP Scripts and Record-Locking: What Every Webmaster Needs To Know - Of course...


    (Page 5 of 7 )

    Answer: Performance

    Of course, all webmasters are aiming to build busy high traffic
    web sites... but will your scripts be able to handle the load?

    Go back and re-read the paragraph on file-locking. Now think about
    what would happen if all the classified ads on your classified page
    were stored in a single file (or all the links on your top site, or
    all the subscribers to your autoresponder, etc.).

    What would happen?

    Answer: Because each update can only be performed after the previous
    update has been completely finished, your site may be slow, or even
    unable to handle all your users' requests.

    So what's the solution?

    There's two options that programmers can use:

    1. They can use lots of small files and file-lock each
    individually (for example, one per classified, one per top site
    listing, etc.). Of course, this needs to be handled very
    carefully...

    2. They can use a database (like MySQL), as databases allow any
    one individual record ("row") to be updated, even when another
    is also being updated.
