I have Install sql server 2014 r2 and iis 8.5 on Windows server 2012 r2
The problem is if there are more than 200 users at the same time IIS will stop working
and will be very very slow and get time out
The processor not up max than 50% and the Rams as well
Is there any solution to that problem

What's the concurrent connection in IIS manager？ Please check the maximum concurrent connection in website advanced setting->behavior/limit.
Besides, could you provide the error message in IIS log,event viewer and http.sys？ In addition, if there is no error message but just hang. Please check the performance monitor to monitor the GC gen and use debug diagnostic tool to analyse the dump file.
You may also need to care about which side restrict the concurrent connection。 IIS or sql database？
