no. Very strange, seeing as sync protocols should have nothing to do
with it.

Why is C slower than B in your setup? Does your secondary have an
inferior I/O stack? I'd advise to match the peers' hardware and switch
back to protocol C in that case. Otherwise, you should really try to
find out what's making it slow, because it shouldn't be.
