What speedup justifies an optimizetion?
27
Normaly with clean&simple optimizations and widely used codecs a overall
28
speedup of the affected codec of 0.1% is enough. These speedups accumulate
29
and can make a big difference after a while ...
30
Also if none of the following gets worse and at least one gets better then an
31
optimization is always a good idea even if the overall gain is less than 0.1%
32
(speed, binary code size, source size, source readability)
33
For obscure codecs noone uses, the goal is more toward keeping the code clean
34
small and readable than to make it 1% faster.
