slow server

For reasons lost in the mists of time (I think I was chasing some bug), I do
"zctl ret" near the end of my zwgc startup script.  Frequently these days,
that gets a timeout when I start up zwgc on tsx-11.

When I investigate this, I usually find tsx-11 talking to arilinn.  According
to zstat's "packets handled" data, arilinn is getting only a couple packets
or so per second.

Since only (some of) the machines with "zephyr-test" zcluster data are using
arilinn for Zephyr service, and I'm doing this investigating at times when
I'd expect low usage, low rate isn't surprising.  But arilinn is a DECstation
of some flavor; it's got no excuse for timing out.  Any clues as to whether
it's the network, the machine, or the server?  (The server is optimized,
isn't it?  Is it compiled for profiling?)
