Performance Metrics

Using PoWA has a minor negative impact on PostgreSQL server performance, and it is difficult to accurately assess this impact because it may come from different parts.

You need to activate at least the pg_stat_statements plug-in and other supported Stats plug-ins (if any). These plug-ins may slow down your instances and you are advised to choose an appropriate method to configure them.

If you do not use the remote mode, the data is periodically stored locally. Overhead varies with snapshot frequency and the disk usage affects backups.
