1. A method for estimating a level of concurrency, comprising: determining, by one or more processors, an estimated level of concurrency of a device; determining, by one or more processors, a first average response time, wherein the first average response time is an average of response times of a first set of operations of the device; determining, by one or more processors, a second average response time, wherein the second average response time is an average of response times of a second set of operations of the device, wherein each of the second set of operations is initiated under conditions of minimal interference of the device; determining, by one or more processors, a threshold based on the estimated level of concurrency; and updating, by one or more processors, the estimated level of concurrency based, at least in part, on a ratio of the second average response time to the first average response time.
