I'm a professor of computer science at Northern Michigan University. Three students and myself have been benchmarking the Linux kernel. At http://euclid.nmu.edu/~benchmark you will see graphs describing performance for mmap() and page faults. Both graphs show a huge improvement between 2.2 and 2.3. We see a 100x performance gain. My questions is ... Why has performance improved so much? What changed between 2.2 and 2.3 to account for a 100x performance improvement? -Much Thanks -Randy -- ======================================================================== || Randy Appleton, Professor of Computer Science at Northern Michigan || || University.
