I tried that last night and was surprised, so will share.
Creating str of size 1048576.. done.
Converting to binary.. done.
Executing STR copy 30 times... done.
Executing BIN copy 30 times... done.
BIN: Mean: 139461.1, stdev: 7829.9
STR: Mean: 79089.4, stdev: 53349.0
No matter how hard I try, I cannot outperform lists.
