Tranformation time

Discussion in 'XML' started by Tomislav Jakopec, Nov 2, 2005.

  1. Hi to all!

    I have one (or more) problem. I set up a system to provide web access
    to legacy application. Legacy application run at RISC mashine, web
    server is tomcat an linux. Response time is very bad (1000 - 3000 ms).
    First, I think it is RISC fault, but after few test I found out that
    RISC time (invoke method) id app. 300 ms and tranformation time (XML ->
    XSL) is app 700 - 3000 ms. Linux Mashine is CELERON 1,3 MHz with 512 MB
    RAM. Parser is XERCES. All my software effords to lower that time is
    failure (put XSL in to web app context, RAM DISK, ..). Will better
    hardware help? Will another parser help? Witch one? What am I missing?

    TNX!

    * Put Apache in front of tomcat. Preferably httpd-2.1.
    * Use mod_transform on Apache for XSLT - faster parser.
    * Pre-compile and cache your stylesheets at server startup to
    reduce per-hit runtime.
    * Use mod_cache (but only if you're using Apache 2.1).
