Differences Starting with Confluence 5.8 - 9.x
There was a significant change in configuration values between Tomcat 7 (before Confluence 5.8) and Tomcat 8 (after Confluence 5.8). Confluence administrators should review their server.xml configuration and make adjustments.
| Max Connections | Default Max Connections | Wait Time for Connection from Pool | Default Wait Time for Connection from Pool | Example Settings | |
|---|---|---|---|---|---|
| Tomcat 8 | maxTotal | 8 | maxWaitMillis (in milliseconds) | -1 (no limit) |
|
| Tomcat 7 | maxActive | -1 (no limit) | maxWait (in seconds) | 30 (seconds) |
|
Why is this Important?
Some customers have reported slow pages and related problems after upgrading Confluence. This is a likely consequence of running out of connections and having to wait for a connection to become available. The new default of 8 is very low for many higher volume use cases. This is exacerbated by a no limit wait which provides no feedback to page viewer that there is contention. By reviewing your previous configuration and updating it to use the new parameters, it should restore previous behavior.
