Palvelinsäikeiset

Palvelinsäikeiset refers to a programming concept related to handling multiple client requests on a server. In this model, a new thread is created for each incoming client connection or request. This dedicated thread then manages the entire lifecycle of that specific request, from receiving it to sending back a response. The advantage of this approach is that it simplifies the programming logic, as each request is handled in isolation. Developers can write code as if they were dealing with a single client at a time, without needing to explicitly manage concurrency issues within the request handling code itself.

However, creating a new thread for every single request can have significant performance implications, especially under heavy load. Threads consume system resources, including memory, and the overhead associated with creating, managing, and destroying threads can become substantial. If a server receives a large number of concurrent requests, it might exhaust available system resources, leading to slow performance or even server instability. This limitation has led to the development of alternative server architectures, such as thread pools, event-driven models, or asynchronous programming, which aim to handle a greater number of concurrent requests more efficiently by reusing threads or avoiding dedicated threads altogether for each request. Despite its drawbacks, the palvelinsäikeiset model remains a conceptually straightforward way to understand basic server-client interaction.
