MONITORING AND OPTIMIZATION PERFORMANCE MONITOR AND NETWORK MONITOR PERFORMANCE MONITOR Windows NT Object Counters in Performance Monitor OBJECT PURPOSE Cache L2 cache performance Logical disk Mass storage performance, including network storage Memory Memory performance and usage Objects Process and tread counts Paging file Virtual memory usage Physical disk HD performance Process Performance of executing processes Processor Processor(s) performance System Windows NT performance Thread Individual thread performance You will also see objects for each network service installed. MONITORING FOR PROCESSOR BOTTLENECKS MAJOR PROCESSOR RELATED COUNTERS TO WATCH: Processor: %Processor Time - How busy the microprocessor is. Processor is a bottleneck if sustained >80% Processor: Interrupts/sec - Rate of service requests from peripheral devices. If you have a high rate of interrupts/sec with no corresponding hardware functions then you may have a bad piece of hardware. Should be between 100 and 1000. Spikes to 2000 are ok. System: Processor queue length - Number of threads waiting to be serviced. >2 then processor is a bottleneck. Queue length will always be zero unless you are also monitoring a thread specific counter (Context switches/sec is number of threads switched/sec by the processor and is good to use). MONITORING THE DISK FOR BOTTLENECKS IF THE DISK LIGHT IS ON ALL THE TIME, YOU NEED MORE RAM More Ram will increase the size o...
