I don't think PHP/MySQL is the main problem right now, but rather the size of the page. See http://www.websiteoptimization.com/services/analyze/wso.php?url=http://www.jobarray.com/ for a report and some suggestions.

The trouble with that web page is it needs to access 4 external stylesheets and 9 external javascript files before it can be rendered. I think that without changing the size of the data if you made a site wide stylesheet, grouped your javascripts and used gzip then your site could load in one quarter the time.

As for the PHP page alone that takes 1.8 seconds for me to receive. That page is 54 kilobytes. If you gzipped it it would be 11 kilobytes.

Something I didn't know at all!

I'll implement some changes and see how things go.
