How to analyze mySQL performance in PHP pages (memory problems)

Hi.

 

Working with PHP 4.4.2 and MySQL 4.1.19, I'm suffering some memory problems on my server (memory allocations, slowness), and would like to know if my mySQL queries are well-designed in terms of memory.

 

My website allow users to register and to share items with several degrees of privacity, so each time someone accesses webpages I must check which items are public or not, by using SQL queries. I've written code by myself so I may've done some mistakes.

 

Is there any way to check this mySQL performance? Some tips?

 

Thank you very much.
