description In a computing system, an application thread is executed on a hardware thread. Based on a configuration of the computing system, a first threshold is determined comprising a threshold percentage of execution time spent servicing a set of interrupts to the application thread relative to a total execution time for the hardware thread. For the hardware thread, a length of a first time period spent servicing an interrupt in the set of interrupts and a length of a second time period spent executing the application thread are measured. A cumulative percentage of execution time spent in the first time period relative to execution time spent in the first time period and the second time period is calculated. Responsive to the cumulative percentage being above the threshold percentage, interrupt servicing on the hardware thread is disabled.
