With so many profiling tools available, choosing one might pose a challenge – after all, how do you know which one will suit you best? You need to look for a program that measures exactly those parameters that you need to improve your code and is non-intrusive at the same time. In this article, we shall help you make the right decision by presenting a couple of code profiling tools for different programming languages. Did we spark your attention? Then read on!

What to Focus on When Choosing a Code Profiling Tool?

There are several features that you need to look into when selecting a profiling tool, including:

  • Weight – You don’t want your code profiler to be too heavy, especially if you wish to have it running all the time.
  • Purpose – Do you want to run regular checks or perhaps have a code profiling tool running in the background and reporting issues right away? This might affect the type of profiler that you will opt for.
  • Type of data you wish to collect – Not every profiler collects all data – it would be inefficient and difficult to report in a clear way. This is why you should first consider what information you need before choosing your code profiling tools. Then, you should select the best program that collects that particular type of data.
  • Ease of use – Some code profilers don’t come with a UI at all, and you need to type lines of code yourself; others offer intuitive interfaces and are easy to navigate. Some produce detailed, difficult-to-read reports; others visualize data for you. When making the choice, you should take your expertise and resources into account to ensure that the ease of use matches your/your developer’s proficiency.

What Are the Best Code Profiling Tools for Different Programming Languages?

You want to use different tools for .NET profiling, Java, Python, etc. This is why our list of the best code profilers was broken down into separate coding languages – you will know what tool to choose in your particular situation.

Python Code Profiling Tools

What are the best Python profiling tools available? Here’s a list of our choices:

  • Timeit – This profiler lets you measure the relative run time of particular functions within your system. It provides you with extensive details but has one downside: you can run it only on isolated lines and blocks of code.
  • cProfile – The most common Python profiling tool. It’s present in the standard library and provides you with information about call behavior, the total run time of the entire code and each line and details on the frequency of calls for particular functions. However, it generates a lot of data, so you might need some time to extract the truly important information.

Java Code Profiling Tools

What are the best Java profiling tools available? Namely:

  • Java VisualVM – A visual tool with a number of functions, including code profiling. it offers both CPU and memory profiling and is lightweight, so you can run it without impacting the performance of the system.
  • JProfiler – Intuitive UI, a plethora of profiling options (performance, memory usage, memory leaks, threads), this is an easy-to-use Java profiling tool beloved by many developers. Add the fact that you can run it on remote applications to the mix, and you get a truly state-of-the-art profiler.

C# Code Profiling Tools

What are the best C# code profiling tools? In our opinion:

  • Visual Studio Profiler – Integrated into Visual Studio, this C# profiler offers you a wide range of options, including CPU, memory, and concurrency profiling.
  • dotTrace – SQL queries and HTTP requests profiling, garbage collection workload distribution, I/O analysis, and static methods testing are just a few of the features of this excellent profiler.

C++ Code Profiling Tools

What are the best C++ profiling tools? In this case, you should opt for:

  • VTune – Being a part of Intel System Studio, this profiler is an excellent tool for improving your app's performance. One of its greatest strengths is that it supports Linux operating systems, so you can easily run it on your embedded devices. The only downside is that you need to use Intel hardware in order to run it.
  • Valgrind Massif – This is an excellent C++ profiling tool if you wish to evaluate memory usage and leaks. While it truly does the job, bear in mind that it’s relatively slow, so you might need to equip yourself with patience if you wish to use it.

PHP Code Profiling Tools

What are the best PHP profiling tools? Here you can choose from:

  • Xdebug – One of the oldest PHP profilers that is still popular. It will help you collect data about script performance and identify which code parts are slow. Xdebug analyzes code line-by-line and lets you export the collected info into data analysis programs to find all issues more quickly.
  • Prefix – A tracing profiler. It’s lightweight and enables you to catch errors and potential lines that need improvement on a daily basis. Additionally, you can use Prefix, even during the development stage, to locate problems on the go.
