Caching the primaryInstrumentationName#10477

dougqh · 2026-01-29T22:16:13Z

What Does This Do

Caching the primaryInstrumentationName to avoid repeatedly calling instrumentationNames and constantly allocating a String[]

Motivation

Avoid repetitive work and memory allocation

Additional Notes

The high load benchmarks are known to be flaky, but I wanted to double check the regressions anyway.
In a local load test, this change performed as expected...

equal to master on Spring PetClinic 64MiB heap
slightly than master on Spring PetClinic 256 MiB heap
