Hi There! I''m writing an UDP server at the moment. It''s supposed to handle a MMORPG, so there''ll quite a lot of connections. Now, since I''m using UDP I''ll have to sort messages and kinda put them on a stack or something. They way I implemented it now, is that I got a thread the calls recvfrom(); all the time and sorts the received package onto the stack of the connection. Then the other thread just works of the messages from the stack. Now I wonder, would it be cleverer to put them together in one thread and make the socket non-blocking or is it ok to have 2 threads? The way I''m thinkin'' about that right now, is that I''ll stick to the 2 threads, cause it''ll use dual processor systems if available (I hope and then the 2 threads will split up fairly well. (I''ll have another thread to handle the world/AI and other game stuff, but that''s another story .. Ok, tell me what you think ''bout that.. thx, cya, Phil Visit Rarebyte! and no!, there are NO kangaroos in Austria (I got this questions a few times over in the states

I would suggest a queue; first in first out...stacks are first in last out...might not work out too well for yah wiht a stack.

I see with no problem with 3 threads (main thread and 2 networking threads); Windows should only give each thred the processor power it needs…or at least it should if it doesn''t! I thought about doing this then got to thinking…hey I don''t have high bandwidth so the amount of data I''m sending over the net is minimal. I figured the game will be running at 30+ fps so the gap between frames updates to the server is not that bad. Since I don''t need to have *that* much info going out I deticated only a little part to my thread that sends stuff out (MAYBE 2 packets most likely 1 per every 3 frames); most of my data is comming in…no need to add in another thread, but yours might be different.


Hope this helps…if not sorry

ok! thx!

What I meant with Stack was actually a Buffer, so... (A Linked List and is sorted by the 2 byte index I send with every package as an index. lowest one first. So you think I''m doing fine oki... great!
