+Here's a sample little tight counter loop, running for 10 seconds on 3 different setups:
+
+**MicroPython on Teensy 3.1: (96Mhz ARM)**
+
+    endTime = pyb.millis() + 10000  
+    count = 0  
+    while pyb.millis() < endTime:  
+        count += 1  
+    print("Count: ", count)  
+
+**Count:  396,505**
+

+
+**C++ on Teensy 3.1: (96Mhz ARM)**
+
+    #include <Arduino.h>  
+    void setup() {  
+        Serial1.begin(115200);  
+        uint32_t endTime = millis() + 10000;  
+        uint32_t count = 0;  
+        while (millis() < endTime)
