Fantastic read.

In terms of connection pool sizing, I highly recommend the work of Toon Koppelaars. (reference: [neooug.org/gloc/Presentations/2019/Koopelears\_Con…](https://www.neooug.org/gloc/Presentations/2019/Koopelears_ConnectionPoolSizingConcepts.pdf))

which recommends pool sizing as:

min = max = initial.

The TL;DR rationale from the presentation for that recommendation is:

-   unused pool sessions are idle, they do nothing and consume minimal resources because the last thing pool-based apps do is free their resources when they give back a connection. If they dont, then you've got an app bug not a connection pool config issue.
    
-   the max size setting (by definition) is what you are prepared to let your server handle without undue stress, so why would you pick a min/initial less than that, because to do so means yours apps incurring the cost of creating a connection pseudo-randomly. That makes response times variable.
