Moderator,

As you know from experience, having a large total swap area on two
separate drives does improve performance.  I posted our means of obtaining
this primarily because it was long overdue for me to make at least a
piddling contribution to a resource I value so highly.

The line:

config          vmunix          root on rf0 swap on rf0 and rf1

was pasted from the config file which configged with no errors and
produced that machine's current working kernel.  A similar line:

config          vmunix          root on rf0 swap on rf0b and rf0d

is in the corresponding file for this host.

Since a copy of /usr/etc/config was not included in the additional
distribution from our disk controller vendor, I suppose it's a 3.5 vs.
4.x glitch.  The "rf" refers to the Ciprico RF3400 ESDI controller, but I
don't think anything from that distribution is known at config time.

None of our /etc/fstab files reference the swap partition (rf0b) on
the same drive as the root.

I'm relatively new at this, and I'm (happily?) constrained to avoid 4.x
for now, but I submit that my config file is not "wrong", but only
different or perhaps suited to an older system.

[[ Okay.  I won't argue with success.  I didn't realize that you were
running 3.x.  By the same token, you didn't say which version you were
running.  You gave a "blind" answer and I responded.  By the way, are you
sure you are getting all your swap space?  Use "/etc/pstat -s" and double
check the amount.  --wnl ]]
