in the 20-30% range.
also, a few hours after i wrote that, i swapped the 16meggers for
32meggers for 128meg.
the kernel seems to only see 64megs of that on boot. it also seems
[possible disk problem] at around 50% swap on the secondary scsi controller.
this curses lotsa kernel prints, including one about pagein, it has since
spontaneously rebooted various times, and required operator intervention
twice. i'm sure this has to do with the vm...
my personal system had 8 days of uptime with moderate network/disk/cpu
activity today. outside of the memory problems right now, it is really
looking nice.
another interesting thing, since adding a second scsi controller and
hanging swap off of both of those drives, top seems to want to do a
floating point exception prior to getting the second set of samples.
1). how do i get 128megs working right? I've never had to change the
kernel before [bounce buffers was always defined].
The bios and cmos both say 128megs.
pentium/pci, aha0, aha1, ed0, etc...
i really need some help with this one.
i also need sleep.
