A single connection will use a (at most) a single CPU and (at most) one IO at a time.
The normal (non-parallel) replication mechanism is similarly limited.
If you have a query that it taking a long time (because of I/O or CPU), show us the query, plus SHOW CREATE TABLE. We may have advice on how to speed it up (by doing less I/O, etc).
