WITHOUT Pool · every + Acquire runs new Connection()
Waiting queue — requests that arrived when the pool was full
Build a new one, or reuse?
You're in the WITHOUT Pool world. Click + Acquire a few times and watch a brand-new connection get built every time — the created counter climbs with every click and never stops. Then flip to WITH Pool: the counter flatlines at 3 because you reuse the same few.
▸Watch the “expensive objects created” number. WITHOUT a pool it runs away with every click; WITH a pool of 3 it flatlines at 3 no matter how many requests you serve.
