See also the discussions on the upcoming TWikiCache, a build-in caching infrastructure and dependency tracking. Compared to all other caching solutions this one aims at (1) correctness: never deliver outdated wiki content and (2) transparency: no extra provision is needed by the wiki author to get content cached. The TWikiCache will be part of TWiki-5.0. There are backports available for 4.1.x and 4.2.x as well.

On already available performance enhancements, there is also:

• perl accelerators: SpeedyCGI PersistentPerl ModPerl
• using / writing faster skins:
  • less CPU-consuming (few or no %TMPL: and %INCLUDE tags). Do computation more client-side (javascript, ajax,...)
  • smaller amount of CSS & javascript
  • serving (pre-)compressed css & js
  • minimizing the number of http requests to get files (see FirefoxBoosterPlugin
• using long expires on images, css & javascript files
• deporting these files on servers specialized in serving static files
