Many experienced developers have learned how to improve their coding habits to write code that will run faster.

If you have already written an application, it may be tough to determine if you have already registered the code in a way optimized to run at the highest speed.

Fortunately, some tools can help you figure out which parts of your applications are worth the effort of optimizing to achieve speed improvements.

Please read this short article to learn how to use the Scout Application Performance Monitoring tool to determine which parts of a Laravel or Symfony application are worth optimizing and how to use the Scout application tool for free, so you can see it in action without paying.

1. Why You Need to Find the Slowest Parts of Your Application

When you have a complex application that you want to improve its performance, it may be made of many parts that you need to evaluate their performance.

So the first decision you need to make is what part of the application you should start looking for opportunities for optimization.

In general, you should start with the parts of the application that are the slowest because any optimization effort that you make will make a more significant impact on the performance of your application.

2. What Are the Parts of an Application that You Should Optimize First

Once you have a list of application parts that are the slowest, you need to sort them by those that your application users spend more time waiting for the application to complete the tasks that those parts execute.

In PHP Web applications, often the slowest parts are the ones that perform database queries that take more time.

So, even though your application may seem slow, the cause of the low performance of the application may not be in the PHP code itself but rather in the database queries that your application performs.

Still, there may be other parts of your application that are slow. Therefore, you need to find the specific parts of your applications that your users need to wait more time.

3. How You Can Find The Slowest Parts of Your Application

One common technique that many PHP developers use to find out the slowest parts of their applications requires using a benchmark script that measures the time it takes to execute each part of your code that you suspect to be the slowest.

On the PHP Classes site, you may find a few classes to measure the time a part of your script takes to execute.

Although this technique may work in some cases, you may need to spend a lot of time measuring the time that each part of your application takes to execute while the application users are waiting.

4. How You Can Quickly Find the Slows Parts of Your Application Using A Profiler Tool

For problems that may take you a lot of time to solve, the best solution to speed up the solutions is often to use tools.

When finding the slow parts of an application, the tools that can help you solve this problem faster and more efficiently are called profilers.

A profiler tool can collect data from the application execution of the code that makes its parts. Then the tool can analyze to find the parts on which the code is running, and the user is waiting for a response.

Often a good profiler tool is specialized in the type of application that you are developing. So depending on how you build your application, you may need to find a profiler tool that specializes in the applications that use methods or frameworks that you used in your application.

Fortunately for you, if you use either Laravel or Symfony frameworks to develop your applications, there are tools on the market like {link:153:ScoutApplicationMonitoring} that you can use to profile PHP applications based on these frameworks.

Scout Application Monitoring is a performance monitoring application that supports many Web programming languages, including PHP. Suppose you use Laravel or Symfony to build your application. In that case, Scout is one of the best tools I have seen to profile and report performance monitoring information, so you can quickly locate and optimize slow code.

I will continue talking more about Scout Application Monitoring in the following weeks. For now, I invite you to try it by going to the Demo of Scout in PHP, so you can access an exclusive demo page and video demonstrating how to profile a PHP Laravel or Symfony application.
