I’ve been using samply to profile Rastair, a CPU heavy #rustlang CLI tool (it also has tracing for logs but it’s not async). I’m wondering if someone already made a better version of this? I want to filter only for my code, see more details (L1 misses), and compare thread loads

I’ve been using samply as well, but I think there are some Instruments fans out there in the Rust universe? Maybe github.com/cmyr/cargo-i... will help?

I assume this is more powerful but I have no clue how to set up a good template. I’ve been building with debug symbols but also with mimalloc which seems to confuse it a bit… let’s see if I have to dive into this or if there are summary tools for this
