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.

How Much Memory Do You Need to Run 1M Concurrent Tasks?
It would be interesting to bench something extremely lightweight (like https://github.com/edubart/minicoro) against these runtimes.
By my back-of-the-napkin math, 1,000,000 coroutines would cost about 64mb + 2mb/core for stacks.. which works out to about 4x less memory than the 'winner' of this comparison, and ~30x less than go.

How Much Memory Do You Need to Run 1M Concurrent Tasks?
I was sufficiently curious and just went and tested this using BenchmarkDotNet. The example code is here (https://github.com/J-Bax/CSharpBenchmarkExamples).
The difference is quite significant.
(1) With the authors code (using Task.Run), I get ~428MB of allocations.
(2) Dropping the unnecessary Task.Run(...), I get ~183MB of allocations.
(3) Doing (2) and waiting N times on the same delay, I get ~39MB of allocations.
This was all using .NET 6 too. .NET 7 or the 8 preview might be even better since they are working hard on performance in recent releases.
So even looking at just (2), that puts .NET on par with the rust library.
What are some alternatives?
