Determining rcapd Scan Intervals

The scan interval controls how often rcapd looks for new processes. On systems with many processes running, the scan through the list takes more time, so it might be preferable to lengthen the interval in order to reduce the overall CPU time spent. However, the scan interval also represents the minimum amount of time that a process must exist to be attributed to a capped workload. If there are workloads that run many short-lived processes, rcapd might not attribute the processes to a workload if the scan interval is lengthened.
