In a very rough oversimplification, the replication itself is just:
On master: write SQL statements into log.
On slave: retrieve SQL statements from the log on master.
As you may guess this overhead is so small so it probably even can't be
measured.
But understand that slave will run all the data-modifying SQL statements that
are found in log on master.
Hope that's a answer to your question.
