Before doing all of that, use

>
> Show Julia profiling data in an explorable HTML page - GitHub - tkluck/StatProfilerHTML.jl: Show Julia profiling data in an explorable HTML page

and share the flamegraph. Always look at profiles to guide what to optimize. If you post that here I’ll point to the next performance improvement.
