Finished benchmarking commit (dabe9cd): comparison URL. Overall result: ❌✅ regressions and improvements - please read the text belowBenchmarking this pull request means it may be perf-sensitive – we'll automatically label it not fit for rolling up. You can override this, but we strongly advise not to, due to possible changes in compiler perf. Next Steps: If you can justify the regressions found in this try perf run, please do so in sufficient writing along with @bors rollup=never Instruction countOur most reliable metric. Used to determine the overall result above. However, even this metric can be noisy.
Max RSS (memory usage)Results (primary 1.0%, secondary -1.3%)A less reliable metric. May be of interest, but not used to determine the overall result above.

Based on helloworld, the perf regressions seem to be related to the allocator somehow. Previously tcache_alloc_small_hard was called 3 times, now it's called 189 times. The total number of allocations is smaller, but the time spent in the allocator is larger. |

Or maybe the issue is not actually the allocator behavior itself. I suspect that we might have lost LTO on jemalloc and tcache_alloc_small_hard previously got inlined into malloc_default but now no longer is. Possibly updating the host toolchain at the same time so that the versions match will help. |
