The CodSpeed benchmarks were built with GCC 14, the newest GCC on the ubuntu-24.04 image, while performance changes are evaluated with GCC 15 and 16. The ubuntu-26.04 image is generally available, CodSpeed ships its instrumented Valgrind for it, and its default GCC is 15.2. GCC 16 is only a pre-release snapshot there.

Merging this PR will regress 57 benchmarks

2 warnings

⚠️ 537 benchmarks with a significant change ran on different hardware

Their base and head results were measured on machines with a different CPU, core count or memory, so the changes might not come from the code. Run base and head on the same runner type.

⚠️ 720 benchmarks with a significant change ran in a different software environment

Their base and head results were measured with a different OS or toolchain, such as compiler, runtime or library versions, so the changes might come from this difference rather than from the code. Open an affected benchmark to see what changed.
