Finding a bottleneck while loading a webpage?

UPDATE 1:

After running strace on the server, I found that the mmap process takes 90% of the processing time. I found that 1 of the pages takes a minute to load.

So, I found this link: PHP script continues to do mmap / munmap

Perhaps this is the same problem. However, I don't understand what anwer means by correctly disabling php error handlers?

ORIGINAL QUESTION:

How to check bottle neck on my web server when loading a specific web page served by my server?

For some reason, a few pages on my site have become very slow, and I'm not sure where the slowness occurs.

Using an application such as Fiddler or YSlow Firefox addin will help identify slow loading elements on your website. This should make any problems obvious.
