No performance impact at all if the system is lightly loaded.
Performance has to be measured as system throughput after the system
becomes overloaded. Without this change to the scheduler the system
very quickly starts thrashing. It spends more time moving tasks in and
out of virtual storage than it does performing useful work. The penalty
for improved throughput is reduced responsiveness. But that really
doesn't matter since reduced responsiveness will occur on its own as the
system continues to thrash. So there really isn't any single answer to
the question. As I recall the test scenarios showed a throughput
improvement of about 20% within the testing range.
