<ahorek[m]> any hints how to find bottlenecks in Rails? yjit really seems to improve perf, but both jruby & truffleruby are significantelly (8 times) slower and indy makes it even worse. I'm using visualvm, is there a better alternative?
<ahorek[m]> https://github.com/jruby/jruby/blob/master/core/src/main/java/org/jruby/ir/runtime/IRRuntimeHelpers.java#L1468 by tracing memory allocations, this method seems to be hot. Should ```if (useSmallHash) {``` be extracted outside of the loop? It looks like an easy fix.
