Overview
This page provides examples for configuring application server-based data sources across different versions of Confluence with varying configurations.
Confluence 5.8 and higher
These are configuration examples based on Tomcat 8 or higher which is shipped with Confluence versions starting with Confluence 5.8.

Differences starting with Confluence 5.8
There was a significant change in configuration values between Tomcat versions 7 (before Confluence 5.8) and 8 (after Confluence 5.8). Confluence administrators should review server.xml configuration and make adjustments accordingly.
| 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 of our customers have reported slow pages and related problems after upgrading their Confluence versions. 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 connections are very low for high-volume use cases. This is exacerbated by a no limit wait time, which provides no feedback to page viewer that there is a contention. By reviewing your previous configuration and updating with the new parameters, you should be able to restore the past behavior.
