The bottleneck can be at database level, web server level, at php level, or in your php script itself. Try to identify at which level is the slowness.

If all web pages at your web server are s-l-o-w, then you should check your web server configuration.

If other pages (such as html, perl-cgi etc) are fast, but only php pages are slow, then check what may be wrong with php.

If other php pages are fast and this particular page is slow, then check the php code.

I am not a database expert, so can't say much about it. Particularly, check if you can optimize the query that you are using in your php script.

If number of records in the tables are huge, and your query results in output of say 1000 records, then transferring that much data from web server to client (browser) may be slow.
