processes running

[jack]

Kubuntu 7.04 running on a Dell D810 laptop
When I run top, I see a process runnint called migration.  The top line
looks like this:
2   root   RT   0   0   0   0 S 0.0 0.0 0:00.00  migration/0

Anyone know what this process is ?

(Laptop has been running slowly, so I'm going through the processes
trying to find the culprit and also educate myself about the processes
running at the same time)

tia for the input...
