| Hello, Since upgrading XWiki from version 16.10.5 to 16.10.14, we've observed a drop in performance. This manifests as longer page load times, particularly for the navigation panel, which takes a very long time to expand. Even wiki initialization is significantly longer. Here are some details of our setup:
- ~70 subwikis (>1000 pages for the largest one)
- Kubernetes deployment (image xwiki:16.10.14-postgres-tomcat)
- External PostgreSQL 16.4
- External Solr 9.8.1
- OpenID Connect
- Apache Reverse Proxy
We've tried a lot of things (bypassing the reverse proxy, reindexing the database, reindexing Solr, disabling OpenID, decreasing or increasing the JVM size, etc.) without success. Just rolling back the image to XWiki version <= 16.10.10 (without rolling back flavors/extensions) allows for an immediate performance boost in page/panel loading. Based on our observations, we've observed this drop of performance appears in version 16.10.11. The debug information during page load doesn't highlight the panel's slowness. The result after multiple accesses to the same page seems quite similar. I'm including the result anyway, just in case. Do you have any idea what could be causing this slowness and any suggestions for identifying the cause in more detail? Regards |
