In fact, this technology is still available in the traditional socket APM (asynchronous programming model) on the. NET 2.0 platform. The modified buffermanager class is as follows:
Public sealed class buffermanager{//... All fields are private. For the type and name, see the constructor.Public buffermanager (INT maxsessioncount, int distinct evbuffersize, int sendbuffersize){M_maxsessioncount = maxsessionc
. The current thread is related to the current request.2. in ASP. NET, some threads are not always related to requests.
Does it feel a bit difficult? Isn't it easy to understand? Let's continue.
Although in ASP. NET programs, almost all threads should be running in response to requests,However, some threads are not running in response to the request, for example:1. Timer callback.2. Cache removal notification.3. Callback is completed asynchronously in APM

The lab server uses Redhat as its operating system, but one of the biggest problems is that it cannot be shut down normally, or the power cannot be shut down after shutdown. You need to manually shut down the server. So that we have always been accustomed to shutting down the server after the power button is pressed. It turns out that it was an illegal shutdown, which could damage the hard disk. It was discovered yesterday that the power could not be switched off only after the shutdown, and the

a distributed request, such as time-consuming on each node, the request specific to which machine, the request status of each service node, and so on. It reflects the number of services and service levels that have been experienced in a request (such as your system a call b,b C, the level of this request is 3), and if you find that some request levels are greater than 10, the service is likely to need to be optimized.Common solutions are:

read the data closest to the current head) and process it, and the device will return (via Windows) an IRP that represents the completion of the work. The CLR creates a IOCP (I/O completion Port) for each process and maintains it with the Windows operating system. Once the IOCP is placed in the completed IRP (through internal Threadpool.bindhandle), the CLR allocates an available thread to continue the task as soon as possible.
In fact, writing IOCP using the Windows API is very complex. A
