yes, but over thousand of connections its significant. what was a millisecond or less becomes 20ms. so 20x slower. not sure how much impact this has in real lif

yes, but over thousand of connections its significant. what was a millisecond or less becomes 20ms. so 20x slower. not sure how much impact this has in real life, but this is one of the issue with this design (also one of the reason is rarely implemented like this but with HSMs instead)
