Looking for an efficient pure GO approach to copy repeating patterns into a slice, for a toy project, I ran a few tests and discovered a neat approach to significantly improve performance. For the toy project, I am using this to fill a background buffer with a specific RGB color pattern, so improving this performance significantly improved my acheivable framerate.
All the test were run with a buffer of 73437 bytes, allocated as follows
var bigSlice = make([]byte, 73437, 73437)
