My site has a lot of dynamic content, so complete page caching doesn't help, nor does query caching or widget caching, so I had to figure out an alternative to all of this. I installed X-Cache on the server to use as an opcode/bytecode cache (20% speedup) and to use as an extension of WP Cache's object cache mechanism. The latter I found to be immensely powerful. I just surround ANY section of code in the template file (for example a menu) with the following snippet. This way I reduced page generation times from 350-500ms to 50ms. <?php if (false === ($top-menu = wp_cache_get('top-menu','menus'))) { ob_start(); ?> <?php $top-menu = ob_get_contents(); ob_end_clean(); wp_cache_set('top-menu', $top-menu, 'menus', 86400); } echo $top-menu; ?>
