Tsqldbserverhttpapi using the worker thread poolWhen Tsqldbserverhttpapi is created, the default is to use single-threaded mode, and only one database connection is used, and the server should handle a large number of clients relying on only one worker thread (the main thread) and one database connection.The main thread of the server is not too busy to die! Yes, clients don't wait to die!Take code as proof:

A self object, which is the global object representing the worker in this scope. The translation of the Self object is unknown. 1 //Call the Invertimage method, this worker receives a message from the calling script.2 //The ' Self ' object contains the-Methods a Web worker can access apart from those it3 //defines and creates itself4 //The Invertimage me

Prefork (multi-process, each process produces child processes) and worker (multiple processes, each process generates more than one thread)Prefork works by controlling the process after initially establishing a "startservers" sub-process, creating a process to meet minspareservers settings, waiting one second, continuing to create two, waiting one second, and continuing to create four ... This increases the number of processes created by the number of

function to obtain a command from the global command tree. If the command cannot be obtained, call the req_cmd_notification function to add a new command to the command tree. 2) If the command is obtained, determine the type of the obtained command. 3) for the qxl_1__draw type, define a new reddrawable structure and apply for memory for it. 4) obtain the actual content of the command through the parameter information of the command ext_cmd 5) 4. red_push () function Main functions: 1) 5. qxl

I just got into the line for a short time. I will summarize my achievements on two worker class projects. Worker-type projects, commonly known as batch run, are to create a certain amount of data, so that worer can run as much as possible and calculate its efficiency. The general steps are as follows: 1. Stop the application worker. 2. Test Data burial ingP

Create a worker thread that processes a task queueThe number of worker threads is closely related to the number of CPUs, and the more CPUs you have, the more worker threads you can create.VarSi:tsysteminfo;GetSystemInfo (SI);G_decode_handle: = CreateIoCompletionPort (invalid_handle_value, 0, 0, 1);G_work_handle: = CreateIoCompletionPort (invalid_handle_value, 0,

Section 5th service threads and worker threadsWhen you start using it Service , there's always a myth: think of it as Service running in a separate thread in your app. In fact, the Service components, like other components, are running in the main thread of the application, all running on the same single thread.Can be Service simply understood as a no interface display Activity (this metaphor is not accurate, because Service you can invoke WindowManag

1) inherit the Tservereventhandler class, get the basic information of the connecting user including IP and port, so as to monitor whether to save the connection without purgingThe Tservereventhandler class provides a way for the socket to be processed when the user connects and disconnects, which provides two functionsCreatecontext is called when a new user is connectedDeletecontext is called when the user finishes the request processingThe detailed process can be viewed Tthreadpoolserver::task

Suppose we have both workers. Each worker has a ID of 0 and 1 . Also Suppose that we had jobs arriving all the time and each job had Also an identifier 0 or 1 which specifies which The worker would have the to does this job.I would like-to-create 2 threads that is initially locked, and then when II jobs arrive, unlock them, each of them does Their job and then lock them again until other jobs arrive.I have

Recently at leisure to see "Java Multithreaded Design pattern", very good, language is easy to understand, and choreography is good, very enlightening, now pick one of the chapters to write ideas Worker thread is a lot of multithreaded mode we usually use, but we often don't take it as a pattern. The basic content is: There is a pipeline (channel), the line has a client thread client, the other end of the worker
