Question

15. A server is being overloaded by client requests. Explain how the use of threads could alleviate this problem, Explain why you would choose synchronous or asynchronous threading in your solution.

please I need it urgent thanks

Answer 1

   When a number of requests are coming from the various number of clients the server may get overloaded. There are a few signs to know whether the server has overloaded or not. If the server is overloaded there is somewhat delay in the response for the requests from the clients. Generally, if a request takes just one second if the server is overloaded then it takes 1 second to 100 seconds. Sometimes the server releases some bugs. It occurs when the server delivered only a single part of the requested content.

   In order to avoid the overloading of client requests we can use the technique "threading". The first thing we need to defend this problem is to force stop the Work Manager. It helps us to refuse or stops sometimes the newly coming requests to the server and allocates a queue data structure for the past requests. We should also Force Stop the application if there are ideal threads. When the application reaches the admin it comes to the shutdown stage for some time. As above said then all work managers will be shutting down for some time.

   Synchronous threading means that when we are executing some task we have to start the second task at the time when we completed the first task. So here takes much time and also somewhat slowness in the process. If we consider the asynchronous threads we can move to the second task either we have completed the first task or not completed the first task. So asynchronous threading is somewhat easy for the implementation and also we can save time. Thread means a series of processes which are ready to get executed.

   If some requests coming from the clients are stored in some threads and some block of requests will be stored in another thread group it is very simple for the server to receive the requests and also give a response to that particular request in the form of threads.

   In my opinion, if we are using synchronous threads it takes very much time and also very much memory so that we should use only asynchronous threads. By using these threads we can save time as it is moving to the next process before the first process completes. So here the efficiency is also will be more.
