It's 5400 without vs 5500 decicyles with the patch attached. I (still) find it very hard to understand that testing a few bytes of input data has more meaning than running decoding several GBs several times. > Looking at the code, the change introduces one > extra instruction in x64, and is identical in x86, > so I don't really see how it can be faster? I am not claiming it is faster. Just that a slowdown is not reproducible.
