The thread library function performs the following actions to context switch between user level threads:
1. Copy all live registers to Thread control Block (TCB)
2. Restore the state of the thread to run next i.e. (copy the values of live registers from (TCB) to registers)
3. Move to the next thread to execute

What takes longer a context switch with user level threads or one with kernel level threads?
Kernel level threads take a longer time to context switch since OS will have to save and reload each and every TCB (Thread Control block) where as in user level no kernel intervention threads simply context switch more efficiently. But there are disadvantages such as since OS sees the user leve threads as a whole process it will not give a large portion of CPU time for execution if a thread is blocked the whole process goes to the waiting state please correct my answer if im wrong godlovesu49@hotmail.com thanks regards yo
