Also I suspect you only tested in your nice up-to-date system, probably even using multi-threading (which changes the performance characteristics).
While not the same thing, -dr for example gains about 10% on a Apple G4 system.
On many older systems an additional copy of the video will cost you at least 10% performance.
Nothing against optimizing also for more modern systems, but please stop the "I benchmarked on my system, so it must be fine", that should only be a last resort approach.
