  3. I presume they tested WordPress without any caching plugins. Still, good to see that speed improvement.

    My hosting company upgraded to PHP 5.4 today. I ran some load time performance tests on a WordPress install and did not notice any real decrease in WordPress load times after switching to PHP 5.4. But my host’s servers are fast to begin with, so I might not see any benefit from changing to PHP 5.4 if there is any. WordPress using the default TwentyTwelve theme loaded in 656 milliseconds using PHP 5.3.x and 616 milliseconds after switching to PHP 5.4.8. Not much of a difference and the difference could be due to factors other than PHP 5.4.

    • You are comparing the wrong things. I am going to assume 600+ ms is your receive time over the internet which can vary drastically depending on your ISP and other internet weather.

      What I was talking about is rendering time on the server. You should have been looking at timer some templates have in their footer and that should have gone down a little.

      However if you are on shared hosting or something like that and not a vps/dedicated it’s going to be impossible to compare because your environment would be too polluted.

      But if 600+ ms was actually the server rendering time and not transmission time, well then you need a new host. Also make sure your host is using APC or some other opcode cache. And then on the wordpress side you should be using something like wp-super-cache.
