BTW, might it ever be possible, to get rid of maxusers or choose some sane defaults in dependency of the memory size during boot ? 8MB -> 16 16MB -> 32 32MB -> 60 64MB -> 80 128MB -> 100 256MB -> 128 That would perhaps eliminate the problems, when FreeBSD get benched by magazines, that are clueless, to tune the kernel... Additionally... As far as I guess, what's behind maxmem, one could increase some structures behind but not decrease ... If so, would there be a chance to increase it during runtime with sysctl to avoid reboots for testing or if it's sure, that it would have to be increased ? -- Andreas Klemm http://www.FreeBSD.ORG/~andreas http://www.freebsd.org/~fsmp/SMP/SMP.html powered by Symmetric MultiProcessor FreeBSD To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
