I'm working on a Wordpress-powered website (hasn't gone live yet). Most of the time when I load the home page it's fine. Sometimes, however, it freezes for a second on load, before continuing as normal. How do I debug this issue?
A:
Are you testing it on a server or locally?
I've encountered this while developing on a local server, and it's the database access lag usually.

The page wouldn't **freeze** because of database lag, rather it would load slower.. **freezing** to me indicates that the whole browser becomes non-responsive.

I'm assuming freezing means it takes some extra time for the request to be processed. Server side, not client side.

First I would profile your php performance with:
- xdebug using external tools like cachegrind
Next I would also do some base tests with:

+1, and Firebug is also wonderful when profiling the website speed, with its addon: HttpFox

@Mao O man I forget to mention firebug, but you need it to use Yslow and I also believe google page speed! +thanks for +1

A:
Chrome has a developer tool that lets you profile the page and see how much time the browser spends on different things. Its located under developer tools and is called timelines.
I think firebug for firefox can do the same but I have never used that.

A:
Big external resources that require a reflow may block content. Look for complex javascripts and embedded fonts in addition to your general performance analysis.
