 ???  I myself think there goes a good chunk of my sync speed, plus delay :(

Yup.  RS Error Correction is almost always turned on at the same time as interleaving.

One of the things I kept pointing out during the introduction of G.INP is that people tend to use the word Interleaving when really we should be saying Error Protection.   In short, you have INP which uses Interleaving and FEC (RS encoding).  Then you have G.INP which uses retransmission.

Ixel:
Unless you're using a modem which has a Lantiq/Infineon chipset, in which case RS is applied on the downstream whether fastpath or not.

I happen to notice when 'traditional interleaving' is applied. My thoughts are something along the lines of "a bit of sync rate lost and increased latency". As a person who plays quite a bit of first person shooter games online I notice the difference (as strange as it might sound to some), so I much prefer the lowest latency possible. I'd rather have a slightly reduced sync rate instead of 'traditional interleaving'.
