I have two more runs of the benchmark in progress so we will have 3 results for each of the test cases to confirm that the small regressions are repeatable.
They get similar results. Then I tried Linux perf but the hierarchical call stacks, to be used for Flamegraph, have too many "[unknown]" entries. I was using: ./configure --prefix=$pfx --enable-debug CFLAGS="-O3 -march=native -mtune=native -flto" LDFLAGS="-flto" > o.cf.$x 2> e.cf.$x Adding -no-omit-frame-pointer fixes the problem, so I am repeating the benchmark with that to confirm there are still regressions and then I will get flamegraphs.
