@gatorsmile The obvious regression is in schema inferring benchmarks but in
other cases there is significant performance boost even on slower hardware.
@Fokko Could you, please, run the JSON benchmarks before your changes, commit
results and after your changes (also commit it). We will see the difference on
the same hardware.
