Though I cannot show the detail for some reasons, as far as I measured the performance overhead of sync rep by using pgbench, the overhead of throughput was less than 10%. When measuring sync rep, I used two set of physical machine and storage for the master and standby, and used 1Gbps network between them.
Fujii-san, thanks a million. That's valuable information. The overhead less than 10% under perhaps high concurrency and write heavy workload exceeds my expectation. Great!
Though I couldn't contact the testers today, I'll tell this to them next week.
