Performance Test

The performance of lvg, norm, and luiNorm has been improved over years by the following factors:

• Java source code optimization
• Faster database server (IDB -> MySql -> HSqlDb)
• Faster JDBC
• Faster platform (Unix -> Linux)
  • cat /etc/redhat-release
  • cat /proc/cpuinfo | grep "model name"
  • free -mh

Flatform Spec:

OS: shell> cat /etc/redhat-release
shell> uname -a
Processsor: shell> sudo dmidecode
Memory: shell> free -m

• Preparation:

  shell> cd ${TEST}/LVG/PerformanceTest/data/
  shell> mkdir ${YEAR}
  shell> cd ${YEAR}
  shell> cp -rp ../${PREV_YEAR}/Input .
  shell> cd script
  shell> edit * (change ${PRE_YEAR} to ${YEAR})
  

• Run Test (on lexdev):

  shell> cd ${TEST}/LVG/PerformanceTest/bin/
  shell> TestAll
  ${YEAR}
     3
  => It takes 3 hrs to complete
  => Update results to perfoamcne test web page (below)
  

There are lots of new enhanced features implemented since 2005 version. In terms of performance, it's not a fair comparison to compare 2005 release to previous versions. Tables below shows performance test for norm and luiNorm.
