I have to perform load test on a desktop application. So, I used visual studio to test load on web server with 100 users then it worked fine & got no error.
But in real time, I got different behavior on the client side when we do the same activity manually while 100 real users are working together & using that application simultaneously. Client side application is getting crashed/hang or getting UI error due to slowness.
Which tool should I use to test load on both server & client side?
