The good news is that there are hacks that can speed up the entire recovery process, although they all have their own quirky limitations. Patroni, for example, implements one such technique by copying the file named state , which is located in the data cluster’s subdirectory pg_repslot, over to the REPLICA’s data cluster in the same location.

SQL Server According to Bob

SEPTEMBER 26, 2016

Performance issues surrounding Availability Groups typically were related to disk I/O or network speeds. While we were confident in the design of SQL Server 2012, several customers reported to us performance problems that did not appear to be with disk subsystems, CPU, or networks. Now disk I/O and CPU capacity were no longer an issue.
