Which is faster, accessing a variable or a hash value by key? Here is the output on my computer

Benchmark: timing 90000000 iterations of HASH_VALUE, LOCAL_VAR... HASH_VALUE: 2 wallclock secs ( 1.67 usr + 0.00 sys = 1.67 CPU) @ 53892215.57/s (n=90000000) LOCAL_VAR: -1 wallclock secs ( 0.33 usr + 0.00 sys = 0.33 CPU) @ 272727272.73/s (n=90000000) (warning: too few iterations for a reliable count)

Below is the benchmark.
