Limit of concurrent connections

[Martin Defeche]

Hello,

I'm working on three different programs that all uses the same database and
have to run concurrently. In one of them I'm using 3 thread and I use 2
connections for each threads. The other programs use 3 connections.

Sould I use the connection pool for the program using 6 connection or using
9 connections is not too big ?

Thank you in advance.
