This week's giveaway is in the EJB and other Java EE Technologies forum. We're giving away four copies of EJB 3 in Action and have Debu Panda, Reza Rahman, Ryan Cuprak, and Michael Remijan on-line! See this thread for details.
As the name implies, a multiple processor server is a powerful machine that has two or more CPUs. You probably read a lot about multithreading, but what you should retain in this context is that this is just an illusion on a single processor machine. The threads don�t run concurrently, since there is only one CPU. They share the CPU running very fast for small amount of times and to the �necked eye� it looks like they run simultaneously. Multiprocessor machines on the other hand provide real multithreading; two or more different thread can run exactly at the same time.
How session is handled When the server is multi processor server?
In my opinion there is no difference, except maybe the fact that a multi processor server is usually much faster. Regards.
