Real-time != Real fast.......

Real-time indicates a predictable maximum/minimum, whatever is
appropriate for a given resource to be managed.  Since you asked
a question that implied a maximum interrupt latency requirement,
you are designing a real-time system.  Linux is not a real time
kernel, you will need to use something like RTLinux to meet such
requirements.
