Is application side connection pooling always necessary to have good response time?

MySQL has a really fast server side connection pool.

Usually 15 or 20 ms hit to make a new connection even in MySQL.

Also adds a fairly big server load. I suspect if a given MySQL instance supports 1000 long lived connections.. it would only support 100-200 connections that are closing every request. (Have not benchmarked this side, would be curious to see )
