Hit the ground running. No need for intrusive markup of your code.
Best-in-class visualizations let you explore and recognize performance problems with minimal effort.
Annotating your code means bias towards where you think the problem is, instead we show you where it really is.
Get the big picture by going beyond the bare statistics. Understand why, when and in what order your code is executing.
See what really happens under the hood when you perform that system call. It’s like having X-ray vision.
Unprecedented precision through our high frequency sampling engine (8KHz+). When needed, add even more precision through use of our API.
We won’t ask you for any personal information. Promise.
Superluminal is an utter joy to use. I went from download to profiling in five minutes. An hour later, several embarrassing performance issues were made painfully obvious. After just four days, I got our frame-time down from 50 to 20 milliseconds. It also helped us find and fix a number of concurrency problems that reduced our load-time from 5 to just 1 second. Thanks again – easily the best money I’ve spent on any software tool.
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.
