work,i/o最小线程设置

设置work i/o最小线程有两种方式
1.通过配置文件设置，影响所有iis部署程序（待验证）
2.通过程序代码设置，iis上部署的程序互不影响
int minWorker, minIOC;
//Get the current settings.
ThreadPool.GetMinThreads(out minWorker, out minIOC);
//Change the minimum number of worker threads to 300, I / O  threads to 200
ThreadPool.GetMaxThreads(out minWorker, out minIOC);
ThreadPool.SetMinThreads(600, 600);
