I have to Listen device from Server.I have 1200 devices What is the best way listen 1200 device from one server? (Multi thread or another way)

Answer 1

Event-driven server is a requirement here.

Forget about Indy, and use an event-driven (aka over I/O completion) IP server.

Windows limit is around 2000 threads for 32 bit, since each thread reserves 2 MB of stack space, AFAIR. A server like Indy will use one thread per connection, so it will be just a big waste of resources.

By design, I/O completion allows to balance all the incoming requests to a small thread pool. See Is there a I/O completion port based component for Delphi? and Scalable Delphi TCP server implementation

Check out ICS which is an internet library which allows you to manage many connections from a single thread. Ideal for your purposes.
