For example, in the following illustration shows that line number 54 in the index.php script was visited 3 times, the application spent 1.4276 ms on average executing this line, the total time of the execution was 4.282 ms, minimum time spent was 1.273ms and maximum time was 1. The data in each column of the PHP profiler report can be sorted, providing an easy way to view the PHP performance profile of your application from any perspective. The Upper horizontal bar represents the total time and the lower bar represents time spent on each line when it is executed. Unlike most code profilers, this one allows you to specify exactly what parts of your application to profile. The YUI Profiler is a simple, non-visual code profiler for JavaScript. The most time consuming line is set at 100% and the rest of the times are shown as fractions of the longest time interval. YUI PHP Loader Grid Builder » Skin Builder » YUI > Developer Tools > Profiler Version 3.10.1. In addition to this PHP application performance data, there is a chart column, which displays a graphical presentation of relative execution time of every line of PHP code. Maximum time spent in each line of code in PHP script.Minimum time spent in each line of code in PHP script.Total execution time of each line of code in PHP script.Average execution time for each line of code in PHP script.The number of times or 'hits' that each line of code in PHP script was run.The profiler report displayed in the PHP Profiler output table show: The PhpEd PHP Profiler tells you which PHP scripts are the most time consuming. (Viewing PHP profiler results - Click to Enlarge) How does the data above changes when you run through the application multiple times, under heavy load?Ī PHP Profiler can present all of this information in easy to read, graphical form, allowing you to find and fix potential PHP application performance problem areas.What are the lines of code, function calls and class methods which are most frequently visited?.What lines of code, function calls and class methods is the application spending most of the time? As someone working on tracing/profiling extensions myself I have to say this is very nice The live output.Which PHP scripts take the longest time to run?.The first step in tuning of the PHP Application's performance is finding the bottlenecks. You'll learn how to identify which lines of PHP code are the most time consuming, which lines of code are most frequently visited, and many other important benchmarking and optimization techniques that will help ensure that your programs run fast. This tutorial covers how to use a PHP profiler to improve application performance. The problem is that PHP applications always run super fast when there are just 3 records in your database and you're running on localhost – these assumptions are not valid for real world applications. Nobody aspires to write slow applications, yet there are a lot of really slow Web applications out there! Unfortunately, the performance of an application often takes a back seat during development and sluggish application performance only becomes a critical problem after it's deployed to the Web.
