testing - Jmeter deviation vs throughput -

-

can give some.explanation on how interpret deviation vs.throughput? 1000++ deviation result means poor performance of web under test? , how can web under test performs good? base on.throughput result? how?

and listener best tracing load/performance of thousand users

lastly possible check cpu/ram usage of server while pwrforming test

  • standard deviation quantifies how response time varies around mean, or average. not advisable judge system performance based on standard deviation. in reality gives how system fluctuating. deviations should minimum i.e. less 5%.

  • thoughput defined number of requests processed per second.

  • it better use throughput factor judge system/application performance. higher throughput means system performance again depends on choice. critical systems low response time more required high throughput. throughput states how concurrent transactions system can process per second might mean high response time. if response time increases beyond limit system considered performance tuning.

some systems throughput means

  • you can either use summary report or aggregate report listeners.

  • cpu/ram usage, can use "jp@gc - perfmon metrics collector" jmeter plugin.

hope help.
