Benchmark tool

[code green]

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.

A simple class that tells the truth is all I need

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(explo de(' ', 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:

$t_start = array_sum(explode(' ', microtime()));

// Some code

$exectime = round(array_sum(explode(' ', microtime())) - $t_start, 4);
echo "Execution time: " . $exectime;

Will give you the time it took to process "some code" to a precision of 4 decimal places. Works well for me.

Hopefully this is somewhat close to what you were looking for.

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('Fla g 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.

I use XDebug in combination with a cache grinder.

I use XDebug in combination with a cache grinder.

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.

I need to identify this type of thing.

XDebug is a PHP extension which provides debugging and profiling capabilities.

a cache grinder is a tool to make profiling information visible (cf. KCacheGrind, webcachegrind and the additional info at XDebug)
