Comment: Server hardware enhancements and other bits below it

...

  • RAM - Java applications like Confluence love RAM. It's a very quick way to squeeze some more performance out of an existing server that's struggling under the workload. If you have over 1GB of RAM in your heap and you're still running out of memory – profile the dumps for memory leaks.
  • Faster disk drives - if you use macros that make heavy use of the search index (you'd be surprised how many do this!) or database then investing in a faster disk drive will help boost performance. We generally use 2 or more 7200RPM SATA drives in RAID 1/5 configuration via a hardware RAID controller.
  • Faster processor - A faster processor will, erm..., process things faster! For best results invest in a multi-processor server and use dual- or 64-bit server with modern multi-core processors.

Clustering Confluence

We made Theme Builder 3 clusterable for a reason (wink) If you are following these guidelines, you need to cluster will mainly come from the desire for high availability to reduce the risk from hardware failure.

Other Options

There are a vast array of other options, including changing or optimising your application container (eg. Tomcat or Resin), operating system, database and cache settings.

If you host or access the database and/or file system on another server using something like NAS, you'll likely be adding a huge amount of latency, compared to local storage, as a result. Instead of using remote file storage, look at pushing the attachments into the database and taking manual backups – this will substantially reduce the amount of size needed for the Confluence home directory (potentially multiple TB reduced to under a 100 MB).
