Availability Zones beginner
A nightly close job commits 120000 single-row transactions one at a time and finishes in about 2 minutes. After the team enables synchronous multi-zone replication on the managed database the same job takes about 5 minutes with CPU unchanged on both primary and standby. Estimate where the extra time went and say what the same arithmetic implies about synchronous replication across regions.
