My machine is running Ubuntu 18.04, but I would expect the OS to make little difference to such figures: the build options for perl would be far more important. For my 5.34 the relevant ones are -Dcc=gcc-9 -Doptimize="-g -O6" -Duse64bitall. In particular it would not surprise me if a -DDEBUGGING build slowed down operations on blessed coderefs relative to unblessed ones.
