ESTIMATION OF APPLICATION PERFORMANCE VARIATION WITHOUT A PRIORI KNOWLEDGE OF THE APPLICATION

摘要

Generally, this disclosure provides systems, devices, methods and computer readable media for estimation of application execution performance variations on a processor, without a priori knowledge of the application. A system may include network traffic data collection circuitry configured to sample a first network traffic statistic, from a network interface circuit associated with the processor, at a first sampling time interval during the application execution. The network traffic data collection circuitry may also be configured to sample a second network traffic statistic from the network interface circuit at a second sampling time interval during the application execution. The system may further include performance analysis circuitry configured to calculate a ratio of the first network traffic statistic to the second network traffic statistic and to estimate the application execution performance variation from the first sampling time interval to the second sampling time interval, wherein the estimation is proportional to the calculated ratio.
