My non empirical findings thus far:
1) Camera startup time (from power off) to ready state, seems twice as fast.
2) image (DNG) write time seems faster
3) thumbnail WIFI upload to iPAD Mini 4 Retina (11.0.3) is faster
4) Save of full size JPEG to above iPAD seems faster:
Overall I am most pleased with these speed improvements.
