Maximum connections per second in HTTP.sys (HTTP server functionality) will depend on underlying TCP/IP stack. However, you can configure Max Connections (default=infinite): for a URL namespace that a URL namespace can be reached by. If the limit is
exceeded a 503 will be sent to the client and disconnect.
You can configure this max connections value from the registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\HTTP\Parameters\MaxConnections. For more information on this and other registry parameters please refer to
