If my environment and requirements match yours, you'd need 10000 *
max_pool_size * 66KiB at peak usage. That's about 640MiB for each
connection you want in 10k pools. For a (uniform) max pool size of 4,
you'll need more than 2GiB of heap space just for connection pools.
Is that acceptable?
Taking the same hypothetical case and figures :
Assuming that you need a total of (10000 * 4 connections) = 40000 connections.
Assuming that it takes 10ms to set up one such connection, and that once it is there, you
don't do anything with it and just let it be for now.
Assuming we ignore such things like bandwidth, other things happening on that
host etc..
It then takes a total of (10 ms * 40000) = 400000 ms = 400s = ~ 6.5 minutes
just to set up these connections.
Is that acceptable ?
What I mean is that once you start playing with such numbers, you may want to look at
other aspects than just required memory..
