I have a component that needs to poll a SimpleIPC server repeatedly (at each 1s or so).

Currently i'm using a TTimer with a OnTimer handler that calls FIPCServer.PeekMessage(1, True);.

Wondering if using TIdleTimer, Application.OnIdle(or AddIdleHandler) or a separated TThread will be more efficient.

By efficiency i mean low resource usage, notebook battery friendly

While I do think that polling once a second will not do any noticeable harm, a better design might be to push some kind of message from the other site and wait for same in a function that does an appropriate OS call.

(E.g a TThread doing a blocking wait for a pipe and then using TThread.Queue to call an event handler function in the main thread.)
