Superluminal is the new industry-standard profiling tool.
With full support for C++, you can push your performance optimizations to the next level!
Getting started is easy. Simply install Superluminal and run or attach to your C++ program directly from Superluminal. No code modifications needed.
If you need it, we provide an optional API that can be used to further annotate your C++ program with events that are interesting to you.
Superluminal is the only sampling profiler that displays the profiling data in a visual UI. Sampling data is displayed on a per-thread timeline, which allows you to see exactly what function is being called when, in what order, and what other functions are being called around it.
Understanding the complex interactions between threads in a program can be key in resolving performance issues. These complex interactions are visualized in an intuitive interactive interface that allows you to inspect blocking and unblocking callstacks and easily navigate between them.
High frequency sampling (8 – 40 kHz, depending on platform) allows you to hit the ground running without the need to make any code modifications. Sampling can start right from the start of the application, allowing you to inspect application startup, including DLL loading, the static initialization phase and more.
The source window displays source code along with per line timing and thread state information. To drill down even deeper, a mixed-mode disassembly view lets you view per-instruction timing information. If no source code is available, the disassembly is displayed.
Superluminal is capable of isolating a specific portion of a capture. Investigate unexpected frame spikes, or zoom in to the startup phase of your application.
