Mountain Standard Time (excluding most national holidays). This is an end-to-end performance test from a REST API all the way down to the network. Latency — or lag — is measured in milliseconds and can also be referred to as a ping rate in latency testing. There are switches specifically made for a faster key input, such as the Cherry MX speed switches. PCoIP handles latency pretty good as long as it has a lot of bandwith, high latency and low bandwith is not funny and should be avoided if possible. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in.
