- Calculate the time taken for the execution of your timer interrupt ( right from its delivery till irq return.) - So lets say if it takes a 400 micro seconds. If HZ=1000 configured, then 400us * 1000 is spent in execution of timer interrupt in one second. At a certain value of HZ the total time of every second is just spend in timer nothing else ... effectively the system stops responding to rest of the activities ( since this irq typically has highest priority) ./v "live & let die" -- Kernelnewbies: Help each other learn about the Linux kernel.
