Answer / azannah
Based on the context ("Categories >> Software >> Java-
Related >> Java-J2EE >> Servlets"), "context switching"
occurs when a processor (or core in a multi-core processor)
stops executing one thread to start executing another.
Since a context switch is not a free process, too many
context switches/sec can reduce the overall ability of the
processor to do real work.

The scheduler maintains a queue of executable threads for each priority level. These are known as ready threads. When a processor becomes available, the system performs a context switch. The steps in a context switch are:
Save the context of the thread that just finished executing.
Place the thread that just finished executing at the end of the queue for its priority.
Find the highest priority queue that contains ready threads.
Remove the thread at the head of the queue, load its context, and execute it.

within the same process as the server.
