I then ported the client application over to the Gadgeteer platform to see if that made a difference. I used a FEZSpider running .Net MF V4.2.
I then timed 10 requests to gpstrackerhttpheaders.cloudapp.net
Average 1174 mSec
Average 884 mSec
These numbers are better than the Netduino+ but still not great. I need to go and take another look at my code to figure out what I am doing wrong. For consistency with the Netduino+ I didn’t use the GHI premium Net library but will build a version of the client application which uses it in a future post.
