- the AGE_FACTOR calculation will overflow after the system has an uptime of just _3_ days
Tsk tsk tsk...
Now if you can make something which preserves the heuristics which serve us so well on desktop boxes and add something that makes it also work on your Oracle servers, then I'd be interested.
What do people think of my "adjustments" to the existing algorithm? Mostly it gives extra longevity to low-UID and long-running processes, which to my mind makes sense for both server and desktop boxen. Taking for example an 80Mb process under my adjustments, it is reduced to under the badness of a new shell process after less than a week's uptime (compared to several months), especially if it is run as low-UID. Small, short-lived interactive processes still don't get *too* adversely affected, but a memory hog with only a few hours' uptime will still get killed with high probability (pretty much what we want). I didn't quite understand Martin's comments about "not normalised" - presumably this is some mathematical argument, but what does this actually mean? -------------------------------------------------------------- from: Jonathan "Chromatix" Morton mail: chromi@cyberspace.org (not for attachments) big-mail: chromatix@penguinpowered.com uni-mail: j.d.morton@lancaster.ac.uk The key to knowledge is not to rely on people to teach you it.
