MQTT on ESP8266 with Espruino

I just tried that code (ran it 10 times just to be sure) and the results are:

• 1v80 - 3.83 sec
  
• absolute latest - 3.80 sec, 158 used
  
• latest, but before flat string changes - 3.79 sec, 193 used
  
  

So there is a very small speed difference, but I'm not sure it's noticeable.

I think your slowdown might have been because the GitHub builds I put online still have debug checks in them.
