I was at a Parallel Sysplex and Performance training earlier this month
and the teacher told us, that CTCs ourperform CF signalling paths,
because of the multiple step (write, notify, read) approach for the CF
path versus the single step (what is written is synchronously read at
the other side) approach for the CTC path.

Ahhh... a teacher at a class told you. Then it must be true! :-)
Maybe because *it is* true? ;-)
I was told (almost) the same information. *Almost*.
It was: " *for short messages* CTC outperforms IXC* structures". So, it
depends on the size. What size falls in "short" category - it depends on
speed of links (CTC and sysplex), CF CPU speed and workload.
That's why one can have CLASSDEF statements in COUPLExx.
