What is the BEST Hardware Platform Means to Me

Last week I tried to make my new Intel Galileo running a basic 14 x 7 LED Matrix program which was working perfectly on my old Arduino UNO. This Intel powered opensource platform has a CPU frequency of 400MHz while the Arduino only got 16MHz. The interesting thing I found is, after I spent 3 hours to port the program to Galileo and executed it with full of expectation, the program turned out to work crappy: the LED matrix looked unstable and each pixel had a different luminance.
