1. A method, performed by a computing device, comprising: determining, by the computing device, a mean response time for messages received by the computing device; associating, by the computing device, a first priority level with response times below a range associated with the mean response time; associating, by the computing device, a second priority level with response times within the range; associating, by the computing device, a third priority level with response times above the range; associating, by the computing device, a message feature with at least one of the first, second, or third priority levels; receiving, by the computing device, a message; determining, by the computing device, that the message includes the message feature; and assigning, by the computing device, one of the first, second, or third priority levels to the message, based on determining that the message includes the message feature, wherein the range corresponds to a range of times within a standard deviation of the mean response time.
