Update: As mentioned in the Edison Forum thread, I am now caching the output pin enable object and that has sped up the switch from OUTPUT to INPUT from about 2.8ms to maybe 1.1ms, which I think is pretty good. Currently also making similar changes for Edison gen 2 as it has similar code.
Note: I uploaded the code I am about to test on Galileo as soon as I get things set up (building cmake now)...
Note: On Edison both Output Pin Enable and Pullup resistors are defined in arrays. With the Gen2 Galileo, they are defined as part of the Pin structure, however there still is an external array for the Pull up resistors. If you are interested in the changes, they are in my gpio-speedup branch.
