Another issue that came up is the number of
connections from Openser to
the database. In our case, listening to five interfaces, with tcp
disabled and children=5, we get 28 connections to DB which is a great
waste of resources. From those five interfaces, one is receiving the
bulk of traffic and the rest receive minimal traffic. Since each child
has its own connection, then what is the purpose of connection pooling?
How difficult would it be to have a common connection pool for all children?
I don't think that having 28 DB connections is a waste of resources, in
fact I think you will get better DB query performance using one DB
connection per openser worker process than using a DB connection pool.
Most databases including Oracle DB are optimized for concurrent access
using either a process or a thread pool, so why not take advantage of
that. And most DBs can easily handle at least 100 concurrent DB connections.
