Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

What is your favourite profiling tool for C++?
Omnitrace. Similar concept to VTune and Nsight Systems from AMD: profiling and/or tracing for CPU-only or CPU+GPU workloads: sampling, binary instrumentation, etc. Has more CPU-based information than Nsight Systems and supports binary rewrites for instrumentation which VTune lacks (runtime instrumentation only). Also supports causal profiling like COZ. Supports Python-based analysis/manipulation/filtering/comparison of traces and profiles. Other great tools: HPCToolkit, Caliper, and TAU.

Omnitrace: New Performance Analysis Tool for CPUs and GPUs by AMD Research
I think I actually saw the GitHub issue you filed with Dyninst. I noticed you were using Ubuntu 22.04 which I've encountered issues with myself. If you file a bug report on GitHub with some info about the segfault, I'll see what I can do to track it down.

What is your favourite profiling tool for C++?
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.

What profiling tools you really want to recommend to others?
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.

Tracy: A hybrid frame and sampling profiler for games and other applications
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.

What are the best resources to learn networking for low latency C++ engineers?
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

Should I make my own game engine?
I highly recommend checking out Optick. I use it almost daily at work :)
