Apple thinks secret, but the net never forgets...
Authored by: Cecily on Nov 14, '03 11:28:24AM

Silly question, quite probably - but my rc file doesn't contain the line ConsoleMessage "Starting virtual memory" - it says echo "Starting Virtual Memory" (I'm running Panther). Is it safe to add the extra lines to the rc file just before this line?

Works just fine in Panther. I say "works" meaning it causes no ill effects. Whether it actually does anything is anyones guess. Just a note though - if you are running the default crontasks for os x that run at 3am or so - all bets are off. This process completely whacks out maxvnodes and when you get up in the morning it is ALWAYS at 100%. I guess I shouldn't say "whacks out" what I mean is - it completely obliterates any maxvnodes tuning you have done. Something about touching/accessing hundreds of files so I've read.

pstat -T = 51883 vnodes

I can confirm this. Don't know which script causes this, but I just entered the maxvnodes adjustment, then ran all 3 (daily, weekly, monthly) and now I get:
Mike-Kupietzs-Computer:~ Kupietz$ pstat -T
612/12288 files
  51883 vnodes
swapmode is not (yet) available under Mach
Mike-Kupietzs-Computer:~ Kupietz$ sysctl kern.maxvnodes
kern.maxvnodes = 51904
So... does someone more knowledgable want to comment on what this might mean in terms of performance?
