Mark, By "performance implications" you mean the side effects it has on things like throughput and latency on the master cluster? You're wondering how much of a hit that cluster will take once replication is enabled?
verifyrep only does what its name says, it verifies the replication was done correctly between two tables for a time range and it's not really fancier than that :) Here we have a cron job that checks a table at random every 30 minutes for a 1 hour window to make sure things work correctly.
