Not an answer, but some random apocrypha:


Try prstat, unless you really need something that top does and
prstat doesn't.  prstat should usually use less CPU than top from what
I've read.  (Some of the design choices in top favored portability and/or
scalability over performance.)

Don't leave top (or even prstat) up all the time, unless of course you're
very sure you're the only person on the system doing that.  There are
too many stories of systems bogged down, where the top half dozen or
so processes were (you guessed it) top itself.

If you use top, consider using the -s seconds option, with some number like
at least 15, and preferably 60 or so, unless that would result in your phone
ringing more, some SLA being violated (or if you're a developer, in not
noticing some performance issue that you're trying to spot).  The default
5 second updates mean that top is doing a lot of work, and also are likely
to mean that if it has leaks or other bugs, they'll show up that much sooner.

If you just want to see system load and CPU usage rather than the specific
offending processes, consider sdtperfmeter (on SXCE).  I don't know if there's
a GNOME client for rstatd, but if there is, that would hopefully be on 
OpenSolaris
(instead).
