c# - Load testing server log-in -

i'm developer no test-experience.

i investigating how load test server handles log-ins mobile app. users logs in @ beginning of work-shift. therefor there heavy load during morning when wants log-in. have had issues server crashing high loads , want replicate behavior analyze it.

i got source-code developed application tests logging in, able add list of users , and let them log-in x amount of times. uses backgroundworker, can gather still use 1 thread , requests sent synchronously , not accurate representation of actual load in production?

private void backgroundworker1_dowork(object sender, doworkeventargs e) {     foreach (iclient client in clientlist)     {         runtest(client);     }      } 

how can modify better reflect actual usage? or there easier way test load?

i have looked using tasks , tpl. i'm having trouble wrapping head around it.

if instead do:

private void backgroundworker1_dowork(object sender, doworkeventargs e) {     foreach (iclient client in clientlist)     {         task.factory.startnew(() => runtest(client));       }      } 

will "automatically" start new thread , manage it?

no, wrong backgroundworker1_dowork launching background thread-pool thread , task.factory.startnew(() => { ... }); call. there no point in doing what-so-ever far can see.

i testing serially, why need multi-thread it? like:

private void runloadtests() {     foreach (iclient client in clientlist)         runisolatedtest(client));     } 

in runisolatedtest method can add load testing , ever want. ensure test each client run on same thread (which won't give accuracy in terms of other operations thread taking part in, better spinning off multiple threads!). can @ cpu-ticks or other processor stats required.

i hope helps.
