Is there a good way of gauging how efficent (or not) a script is, especially ones involving database calls?

I can get things to work, but being self taught at PHP I'm never sure whether I'm doing things in the best way Confused

There's a very nice benchmark/timer class in pear (find it in the cvs @ [url]cvs.php.net[/url] under pear -> Benchmark_Timer) which works well. Takes a little bit of getting used to though Smile

You can call microtime() at the beginning and end of the program, and find the difference between the two.

I think this tutorial has everything you need Timing Script Execution from PHPBuilder.com

Trouble with that is you only have yourself as a benchmark, I guess it would be useful for seeing if you have improved something though.

I'm thinking there is no easy answer, accept do a bit more reading, learning and practicing and of course visiting this forum Laughing

A more useful thing to have implimented is for the page to update a log on how long each page executes. Then you can consult the log regurally to see if things are slowing up or what. MySql can be unpredictable, qeuries are queued, the system processor can be tied up with other things, there are many variables.

To see if a new request is better than others, run the PHP script a few times, and get the average of the values. This is a more accurate way of testing page times.
