optick VS tracy

Does anyone here have experience with Optick: https://github.com/bombomby/optick ? It looks great but I haven't got the chance to try it. Was wondering how it compares to the other tools listed here.

As a free alternative, I've had multiple people recommend Optick, but I haven't had the chance to play around with it yet, so I can't vouch for it myself.

I have used Tracy to improve the performance of a latency sensitive application. The main advantage of this tool, in comparison to something like the Visual Studio profiler, is the fact that it can highlight the inter thread dependencies and synchronization between the threads. The other main feature, in my opinion, is the statistical tab that is associated to the recorded events: it can show the statistical distribution of the duration of all the invocations of functions and it allows to identify patterns in the performance of the application. Furthermore, a table can be used to sort the invocations of the functions and quickly jump to the point in time when the sample was recorded.

Other notable tools that implement a functionality similar to what is provided by Tracy are Optick https://github.com/bombomby/optick and Intel VTune (sadly specific to only Intel processors) in the Threading analysis.

we don't do systematic perf measurements beyond prod metrics but if we did the good tools are uiCA/IACA/etc, tracy/brofiler, perf/vtune

I highly recommend checking out Optick. I use it almost daily at work :)

i don't really think there is _anything_ that comes even close to tracy https://github.com/wolfpld/tracy.

on top of this, given google's penchant for dumping projects aka abandonware, this would be an easy pass.

The RemedyBG debugger (https://remedybg.handmade.network/) and the Tracy profiler (https://github.com/wolfpld/tracy) both use Dear ImGui and so far I've only read high praise from people who used those tools compared to the 'established' alternatives.

For tools like this, programmers are also just "normal users", and from the developer side, I'm sure they evaluated various alternatives with all their pros and cons before settling for Dear ImGui.

Not the person you asked, but generally you might want to look at "frame-based" profilers. These are typically used in video games, but the concept is general, and can apply to other applications. The "frame" could also be something like a request or transaction being processed. I like Tracy[1], myself.

Another latency metric that you'll see, often w/respect to web apps and microservices is "P99" and similar. This is the amount of time in which 99% of requests get their response. For a higher percentile, you get a better idea of worst-case performance.

I've not actually used Superluminal, but I use Tracy for similar reasons. It's free though (and, importantly, open source).

For profiling, you can check tracy.

You could try Tracy

There is no such thing as overengineering in fun projects, so I've also adopted Tracy as profiling solution. Works quite nice and gonna save me plenty of times in the future debugging performance spikes on badly optimized math heavy operations.

I know about tools such as tracing, jaeger or tracy. While having a complete tracing could be a potential solution, these tools don't work with no_std.
