I believe each FPGA input channel can handle 40,000 counts/sec. Perhaps someone with intimate knowledge of the FPGA could comment.

Also, are there other variables that could affect the FPGA and how it counts the encoders, and where can I read up to learn more about it?
Download a copy of the WPILib C source code and read the descriptions of the methods in the Encoder and Counter classes.
