Обсуждение: Postgres performance issue
Hi All,
I'm seeing some performance issue that's bulk inserts are around 15 inserts per second which is very low. Do we have a performance mgmt tool in pg like AWR in oracle?
Regards,

I don't know much about oracle or AWR, but you might be interested in pg_stat_statements extension, or pg_wait_sampling (for wait events) and pg_stat_kcache (for CPU/disk usage). There are tools that can perform regular snapshot and display some dashboard based on that, like powa. If that's not enough or what you need, you can look at https://wiki.postgresql.org/wiki/Slow_Query_Questions to provide needed information and get help optimizing your inserts.

You may consider using the Pgbadger tool. This tool extracts data from log files and generates a comprehensive report.
Besides, a low INSERT rate is often attributed to a number of factors.
- A number of indexes
- A number of foreign keys
- A number of DB triggers
- A number of long-running queries
- Another processes contributing to the load
- Disk utilisation
Hope this helps!
Thanks,

Bulk inserts within a explicit transaction, improve the performance.
