I wanted to get a feel for what tools people are using to test the performance of their website.  My questions are:

• Do you check page-load times? 
• Do you dig in to see which files are taking the time
• How do you track down a page that uses a lot of memory
• How do you track down a high CPU consuming page

I don’t want to list any possible tools as I’d like to hear what people are using without me putting any suggestions out.

If I don’t see some being mentioned, I’ll be sure to bring it up so we have a holistic view of the tools.

Look forward to seeing what people use.
