Swapper Process #PID more than 1

Hi
I would like to know more about swapper process..
I knew that swapper is the first process with PID#0, used to perform process swap operations. It used to swap entire processes
But sometimes I find swapper process with PID#264
So my doubt is how many swapper process can exist in a system?
If more than one swapper process exist in a system, will it impact other process?

When in my early days, I kill process 1 for seemingly using lots of CPU, .........

After a boot later and very red face, I learned not to do so again. I am a little surprised that there is a different PID, but depending on your unix flavour, I suppose could be an extra one for each real CPU, but you don't say what you are running.

Swap is a UNIX v7 term. Since BSD 4,1 and System 5 we work based on page demand stealing.

Now if you had been talking about the wait process, I would have something sensible to say.

AIX does not swap - so wrong forums.
