Something changed like below:
<system.net>
<connectionManagement>
<add address="*" maxconnection="999" />
</connectionManagement>
</system.net>
<system.web>
<processModel autoConfig="false"
maxWorkerThreads = "100"
maxIoThreads = "100"
minWorkerThreads = "50"
minIoThreads = "50"
/>
<httpRuntime
minFreeThreads="176"
minLocalRequestFreeThreads="152"
/>
</system.web>

After change the value , the throughput and response time have no changes.

the version of .net is v2.0

Does anyone know why the throughput and response time have no changes after tuning the IIS parameters??
