In AOT this makes reading faster: Output from `out/ReleaseX64/dart pkg/front_end/tool/benchmarker.dart --iterations=10 --snapshot=pkg/front_end/test/kernel_binary_bench.aot.1 --snapshot=pkg/front_end/test/kernel_binary_bench.aot.2 --arguments="--warmups=10" --arguments="--iterations=5" --arguments="AstFromBinaryEager" --arguments="out/ReleaseX64/vm_platform_strong.dill"`: ``` msec task-clock:u: -8.6925% +/- 0.5737% (-167.09 +/- 11.03) page-faults:u: 0.1410% +/- 0.0051% (243.00 +/- 8.71) cycles:u: -10.2918% +/- 0.6161% (-732576747.50 +/- 43853449.16) instructions:u: -14.4988% +/- 0.0004% (-1636799813.90 +/- 39902.18) branch-misses:u: -3.4891% +/- 2.1142% (-1166085.00 +/- 706582.35) seconds time elapsed: -8.7005% +/- 0.5634% (-0.17 +/- 0.01) seconds user: -9.9752% +/- 1.5104% (-0.17 +/- 0.03) ``` Stats running manually (run as e.g. `out/ReleaseX64/dart-sdk/bin/dartaotruntime pkg/front_end/test/kernel_binary_bench.aot.1 --warmups=10 --iterations=5 AstFromBinaryEager out/ReleaseX64/vm_platform_strong.dill`): ``` AstFromBinaryEagerCold: -12.5174% +/- 3.10688% AstFromBinaryEagerWarmup: -8.33675% +/- 2.62433% AstFromBinaryEager: -10.3432% +/- 3.68375% ``` I don't expect there to be much of a change (if any) in JIT as the actual type was in practise always Uint8List anyway.
