Please run one script and report runtime numbers for performance comparison

Can somebody please run the sketch on Arduino Zero?

nathancamp provided both Arduino 101 numbers here.

This is the updated table while waiting for MKR1000 and Arduino Zero numbers:

model -Os -O3 speed processor Wifi
101 846 791 32MHz Intel® Curie -
Due 548 494 84MHz ATSAM3X8E -
MKR1000 48MHz SAMD21 Cortex-M0+ yes
Zero 48MHz ATSAMD21G18 -
ESP8266-12E 612 304 80MHz Tensilica Xtensa LX106 yes
