rtlinux interrupt response

[srinivas pulipati]

hi all,

i have downloaded denx rtlinux and ported it to my custom board for
study purpose.
my board is based on MPC860. rtlinux is working fine.

i tried to measure the interrupt response time.
i am getting best case is 30microseconds and worst case is
150microsenconds.
couldn't understand why this much difference.
can anybody explain? or is there any thing wrong in my port?

thanks
srinivas
