Environment

• Windows 11 64bit version 23H2
• Quad core i7-9750H
• Oracle JDK 21.0.1 (build 21.0.1+12-LTS-29)
• Dumbbench 0.503
• VisualVM 2.1.7
• 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:

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"
