RSA Signature Speed - Simple CPU Performance Benchmark

Measures the time required to compute a digital signature (SHA256 + RSA2048) of a string.

Board Seconds
Teensy 4.0 0.085
Teensy 3.6 0.474
Sparkfun ESP32 Thing 0.518
Metro M4 Grand Central 0.840
Teensy 3.5 0.909
Teensy 3.2 1.325
Arduino Due 1.901
Arduino Zero 9.638

(smaller numbers are better)

You can’t perform that action at this time.
