Dear all,
we have implemented an ASP.NET MVC site that read some data from cache and return json.
The site installed in an WS 2008 R2 machine responds quickly: 165 concurrent requests in about 6 seconds.
But the same site in an WS 2012 R2 machine responds slowly: 165 concurrent requestes in about 20 seconds.
The site is installed in the same manner with the same configuration; we don't have change the default settings of application pools and sites; both the servers are virtual (VMWare).
We try to use Performance Monitor to understand more about the problem: in fact we see that in the first server the Req/s are more than the second server.
What can we do to diagnose the problem?
Thanks in advance.
