最近在测试iis6.0的最高并发数量，在machine.config中修改
<processModel requestQueueLimit="10000"/>
但是在并发数在超过8000的时候，就会返回Service Unavailable
请高手帮忙啊！~~~

CPU usage is typically low. However, requests accumulate in Http.sys. When you use Performance Logs and Alerts to monitor the Current Connections counter of the Web Service object, you notice that requests to the server reach the maximum queue length for requests. By default, the maximum queue length is 4000 connections. After the requests exceed the maximum number of connections, the server returns "503 Service Unavailable" error messages to the clients. An indication that requests accumulate in Http.sys is that the value of the Current Connections counter is very similar to the lesser of one of the following two values:
The request queue length.
The global maximum connections limit for HTTP. The global maximum connections limit for HTTP is 8000 connections on x86-based computers.
