Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. We formulate the problem as a Mixed Integer Program (MIP). can we actually make this work in practice?

Faster detection of a bad connection is accomplished when there’s a lower value, while latency or intermittent network issues may be better served by increasing it slightly – although overly long timeouts can result in application hang-ups with little chance for an established link. The latter refers to how long a socket can remain inactive.
