“Andrea Arcangeli’s recent 2.4.23pre6aa1 kernel introduces some
interesting new dynamic functionality. He explains:“‘Probably the most notable new feature is that you can now pass
‘desktop’ as parameter to the kernel in lilo to ask the kernel to
behave optimally for a desktop machine. No need of compile time
options anymore. For more experienced users HZ=500/HZ=50/HZ=200
should work fine too, then you can tune the timeslices by hand but
you must know what you’re doing.’“Later in the email he cautions users, “Due the amount of
changes you may not want to run this on any production box,”
though noting that it’s the other changes to be concerned about,
not the new ability to dynamically configure HZ and timeslices.
Read on for the full changelog with many more details. Scroll down
toward the bottom of the changelog for more information about
dynamic HZ and dynamic timeslices…”
