Re: Query optimization problem

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Query returned successfully with no result in 600 ms.

Why SELECT takes 3+ second to execute? Is it something to do with my Postgres server optimization, or PgAdmin does not show correct data retrieval runtime (leaks over into query runtime or something)?

Data transfer and display time usually.

Try SELECT count(*) FROM ... instead and see if the times are closer.


Correct. That executes in 300ms flat:

Total query runtime: 301 ms.
Data retrieval runtime: 380 ms.
1 rows retrieved.
