Anybody recommend a reliable benchmark tool for PHP.
I have been using Timer.php which is an old PEAR class, but I am discovering it's accuracy is very poor.
What do you need to benchmark? How long a specific task takes to execute? Resources used? When I need to know how long a task takes I simply create a time_start and time_end variable using this:
array_sum(explode(' ', microtime()));
Then subtract the start from the end and round the result to whatever depth you want. I usually show two decimal places. Full code:
It would be hard work to copy a paste 2-3 lines of code all over the place in some of the huge projects I use.
At the moment I use one line as a marker
$t->setMarker('Flag Name'), and the results are output tidily at the end of execution in a table, rather than buried amongst all the other debugging output.
But Timer.php tells lies. Especially early in the execution where the time can be applied to the wrong marker.
I am just wondering if any has used anything better.
If not I will have to write my own.
That sounds complicated although I have no idea what they are :)
The performance I am measuring are purely database and function / class calls directly on a server.
There is no parsing of web pages or server connection issues (maybe a little, but only on intranet).
For example a script this morning took ~2 minutes in total to run.
The longest section was 48 seconds for a MsSQL query.
