Performance test on Jetty/HSQLDB with a single wiki between 14.4.7 and 14.10

Last modified by Ilie Andriuta on 2022/12/12 16:59

Environment

  • Windows 11 64bit version 22H2
  • Quad core i7-9750H
  • Oracle JDK 17.0.5 (build 17.0.5+9-LTS-191)
  • Dumbbench 0.503
  • VisualVM 2.1.5
  • permdir in a SSD
  • standard Jetty/HSQLDB package
  • only main wiki
  • configuration:
    • Admin user:
      • hidden documents enabled
  • import perf.xar

Most of response time statistics are made with Dumbbench, you can install it using cpan.
For example on Debian/Ubuntu:

$ sudo apt-get install cpanminus
$ sudo cpanm Module::Install
$ sudo cpanm Dumbbench

On Windows 11:

  1. Install perl from https://strawberryperl.com/
  2. Go to Windows Terminal and install Dumbbench:
    PS C:\> perl
    PS C:\> cpanm Dumbbench
  3. (If needed) Download wget.exe (64 bit) from https://eternallybored.org/misc/wget/

    Make a folder for testing the instances and put wget.exe there.

Unless specifically indicated otherwise all the tests are executed with a fully initialized instance (core extensions don't run anymore, SOLR index is fully up to date, etc.) and logged in with Admin user. Basically except for a few special tests we are using an instance that already been started and run until the proc is flat for some time.

Login with Admin user (using port 1115):

.\wget.exe --save-cookies cookies.txt --post-data 'j_username=Admin&j_password=admin&j_rememberme=true' "http://127.0.0.1:1115/xwiki/bin/loginsubmit/XWiki/XWikiLogin?j_username=Admin&j_password=admin&j_rememberme=true"

Tests

Summary

"similar": difference is lower than 10%
"slightly": difference is lower than 20%

Information

Note that most of the speed related values are an average of very fast moving results, a lot of things are happening during a HTTP request and it's far from stable duration (that's why 10% may sounds a lot for something called "similar" but the variable can go up and down around 5% sometimes so 10% average is really not that much of a clear win). Dumbbench based tests are executed several times and the lowest result is selected.

Jetty startup

Unit: milliseconds

This information is obtained from the log with the line looking like 2022-06-15 14:24:27.163:INFO :oejs.Server:main: Started Server@503d687a{STARTING}[10.0.7,sto=5000] @23806ms.

Heap Memory

Attach VisualVM to get the information.

Unit: MB

Heap Memory after jetty startup

Start jetty and wait until Java is not doing anything on both (wait for potential initialization of various stuff like core extension cache, etc). Force garbage collector before looking at "used".

  • 14.4.7: 90 used, 164 allocated
  • 14.10: 96 used, 167 allocated

Heap Memory after full SOLR index

Delete the data/solr folder, restart, load home page then wait until nothing is happening in background. Force garbage collector before looking at "used".

Unit: MB

  • 14.4.7: 243 used, 745 allocated
