Right now, 10-bit decoding is horribly slow because the assembly optimizations only cover 8-bit, so it's probably 10-20x slower. We'll work on 10-bit next, and in the end, I'd expect it to be 30-50% slower than 8-bit.
10/12-bit can usually be done together, but are completely different from 8-bit. However, it's possible we'll do 10-bit first and then later on make the tiny adjustments that allow us to use them for both 10-bit as well as 12-bit.

How much difference in performance is there between decoding 8-bit video versus 10-bit video?

Are 10 & 12 bit decoding in the same optimization bucket or do they need to be treated separately?
