OM Performace Resutls

This page includes the perfomance results of the OM implementations namely the

• The column based table model SVN

• The link list based model SVN

Note the following about the test

Testing framework

• Sosnoski XML benchmark

  The code for the XMLBench is available at SVN

  Please have a look at the guide for the instructions to run the performance tests Guide

Test Environment

• JVM

  Java version 1.4.2_04

  Java Hot Spot(TM) Client VM 1.4.2_04-b05 by Sun Microsystems Inc.

• Computer

  Intel Pentium 4 2.8GHz Processor

  512MB RAM

• Operating System

  Microsoft Windows XP Professional with Service pack 2

Tested implementations

• JDOM

• AXIOM implementation based on the table model (AXTM)

  • tree built completely before walking (AXTM-prebuilt)

  • tree built on deman during tree walking (AXTM-normal)

• AXIOM implementation based on the link lists with tree built on demand during tree walking (AXM-2-llm)

Since AXTM is read only yet, only the build time and the walk time of the implementations were compared.
