Slowness during file transfer.

I'll have to do more of that.
Is there a utility for checking network speed? Trying ftp transfers is a
reasonable "experiment" but kind of klunky.
Anyway...one transfer that was really slow was from another department (say
"X"). It was slow from v1280 to my PC, and between v1280 and X. But not X
and my PC.
But as far as I can tell this could still be a network thing, since it's not
all a single ethernet network; looks like there are different switches in
various places.
The curious thing is that all the cheap Suns with *really* bad problems
(i.e., graphics taking minutes to load, not just ftp slowness) show no
intervening hosts/switches/whatever when I run traceroute. Hosts that show
ftp slowness but graphics relatively unaffected show intermediate switches
according to traceroute.

OK.
Thanks,
