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.

If we are talking replacing the libc allocator, then something like heaptrack is worth mentioning.

How to Perf profile functions?
For accurate memory usage I prefer a memory profiler that overrides malloc and friends instead of the ones that probe the OS at regular intervals. You won't find memory spikes with the latter. Try heaptrack on Linux. I haven't found a good one for Windows yet.

I know it is not a profiler, but it is so criminally underrated that I decided to share it: https://github.com/KDE/heaptrack

My Rust program (Well, game) is leaking memory, 4MB/s.
If none of the above helps - I recommend heaptrack as a tool for tracking down your memory usage.

Lessons learned from 15 years of SumatraPDF, an open source Windows app
> memory leaks. It's surprisingly hard to find an easy to use memory leak detection tool.
I can vouch for heaptrack[1] nowadays, although it's pretty much Linux only. It's under the umbrella of KDE, but a heaptrack trace only requires a CLI app, and there is a nice Qt viewer to analyse the memory consumption.
It tracks the memory utilization at the level of malloc'd/free'd bytes. It's fine if your memory leak or other memory utilization problem is on this level. Recently I dealt with an issue, where increasing memory utilization was caused by fragmentation within the allocator. This didn't show up in heaptrack as an increasing memory utilization, but heaptrack still pointed out where most of the temporary allocations happened, leading to the culprit of the fragmentation.

Memory Leak? Free memory not being reclaimed? What is happening here
When I had this kind problems (heap related) I always use heaptrack. Take a look here for the details: https://github.com/KDE/heaptrack
- Hi, I’m new in rust, I have some expirience with c# and its classes ans structs. I can’t find information about that is happend with struct in rust when I pass it to function argument. Are there some copy effect ?
