How to run? How to measure memory? Rust?

[hissssst]

Hi, thank you for the benchmark and interesting blog post!

I wanted to discuss it with my friends and tweak some code to see how it afffects the result. But I've found out that I need to know how did you measure the amount of used memory? And how did you run the benchmarks?

Plus, your blog post shows rust examples, but they're not provided here.

Here is how to run:

But this measurement is incorrect, since it completely ignores the GC and such stuff. I mean, if we start tasks slower, or induce memory limit, the runtime will be able to spawn more tasks with less memory, sacrificing time for GC

Why not use, perf stat or massif?

to full report:
perf record --call-graph fp program and perf report or valgrind --tool=massif --stacks=yes program
