Environment

• Windows 11 64bit version 25H2
• Quad core i7-9750H
• Oracle JDK 21.0.9 (build 21.0.9+7-LTS-338)
• Dumbbench 0.505
• VisualVM 2.2
• 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"

¹ For the SOLR Sync tests lower times was reported https://jira.xwiki.org/browse/XWIKI-23920, but according to some tests made on other workstation, the time were much better than the ones obtained here.

Jetty startup

Unit: milliseconds

This information is obtained from the log with the line looking like 2026-01-15 14:53:57.343:INFO :oejs.Server:main: Started oejs.Server@74a6f9c1{STARTING}[12.1.5,sto=0] @31804ms.

Full SOLR reindex

Unit: seconds

Note: On XWiki versions > XWiki 17.8.0+, delete the data\cache\solr\search_9 folder, restart, load home page and after INFO o.x.s.s.i.j.IndexerJob - Finished job of type [solr.indexer] with identifier [[solr, indexer]] log, take the last elapsedTime from <permdir>/data/jobs/status/3/solr/indexer/status.xml from status.xml.zip.

Only the thread determining what need to be indexed and not the actual indexing.

Note: On XWiki versions > XWiki 17.8.0+, calculate the elapsed time from the beginning of the Indexing job until the synchronization is done (after the log INFO o.x.s.s.i.j.IndexerJob - {} documents added, {} deleted and {} updated during the synchronization of the Solr index.

The timestamps are found in <permdir>/data/jobs/status/3/solr/indexer/log.xml.
