页面速度 - 测试脚本响应速度

Question

I made a website recent and it's loading very slow. My Firebug Page Speed Score is 82/100. I think this is good. My website has 2 images and they have 100KB and some other small images for bullets, arrows and stuff that have not more that 50KB. Anyway, my point is that the html is quite fast, but I have this html as a Wordpress theme and a new host (cheap one).

My question: How can I find the time for my Wordpress (or any PHP script) to echo out the page requested.

Can I know for sure if the hosting or the script that is making my page work slow?

Thank you!

Answer 1

time your script?

<?php
$start = microtime(true);

  //your script here

$end = microtime(true);
$time = $end - $start;
echo('script took ' . $time . ' seconds to execute.');
?>
