{cbauthor}Go through every single module on your website and turn caching to ON if it is available. If the module has a cache time limit, set it very high if possible. Modules that change content more frequently should be set to a shorter cache time, modules that don't change should have a very long cache time. Keep in mind that the actual caching process will take up more processing time, so set the cache time high enough that most of your visitors will get the cached version and won't have to wait for the module to get cached before viewing the page.
