I did a very simple timing experiement: measure the interval between
two consequtive calls to schedule() function.
Under light load situation, the maximum interval is around 10ms which is
the time slicing interval. However, if I increase the load (actually I
was running NIST POSIX test suite), the maximum interval could go
up to 210ms.
Is this possbile? Should the kernel at very least obey the time
slicing,
which I expect schedule() should be called no more than every 10ms.
Can someone shed a light on this?
