Thread: php and connection

php and connection

From

Hi,
in a PHP application working on Postgres normally the new connection to the database is made per request. 

This can potentially cause too big overhead, so I've got some questions:

- is the overhead really noticeable?
- could this be solved using persistent connections, or the persistent connections in php and postgres don't work properly?
- could this be solved using something like pgpool?

regards
Szymon

Yes, using a connection pooler will solve the problem. I prefer
pgbouncer.

I can't really add to that.
