Hi,
How many concurrent requests can be executed in IIS 8.5.
As I found out below 2 different values :
1, By default IIS 8.5 can handle 5000 concurrent requests as per MaxConcurrentRequestsPerCPU settings in aspnet.config
2, In machine.config, the maxconnection is 2 per CPU as default. So if have 6 core CPU then 12 concurrent requests are possible by default.
