I really appreciate async-profiler to help find performance issues. But there is one thing that it did not make easy: finding small, repeating perf issues.
You have to search for repeating patterns "on the top of the flames" and add their cost.

Yeah, according to the profiler the whole instantiation process takes like 10% of the time, which would give a noticeable boost. I'm pretty sure the rest is just code optimizations (or doing async stuff (which I'm avoiding haha)). Thanks for the tip!

yeah, i profiled with clj-async-profiler and found that in some cases multimethod overhead was as expensive as the actual function called. i experimented with some stuff that made it better, but over the course of it, i wanted to see just how much inlining a static call would perform better or not.

Things should (mostly) be using async: asyncpg, experimental Cloud Trace functions 😬,…

The database query we’re doing is always fast, ~1ms.

Without any further tooling (profiler), I’m kinda out of ideas.

Odd issue w/ using Java async-profiler (3.0.0) on Quarkus app in dev mode, with JDK 21 if that matters. Cannot get non-empty results no matter what (even if skipping `mvn quarkus:dev and running jar directly).
"Profiling started" printed by profiled service yet... nothing gets written.
.. Odd part:
