RE: surprising result:8CPU Sun 3500 VS 4CPU Dell 6650

[John Shaw]

I am also having a weird performance issue with a sun box - mine is a new v880 4 cpu (900mz) with 16g of ram and a 2 T hitachi san. For example - I do an import of a table (partitioned 3 m rows ) and it takes almost 8 minutes vs 3 minutes on my laptop. both running 9.2.0 . many reports take significantly longer on the sun box than my laptop - go figure - I have a tar on it - but resolutions yet. I have uploaded statspack up to oraperf and nothing significant showed up there either. Anybody have a idea I'd be happy to try it.

One thing I noticed is that you were using an older Sun.  The current Suns
have CPU's more than twice as fast as what you are using.  It would be
interesting to see the results using a new Sun rather than an old one.  I
have always thought the Dell PowerEdge series was an excellent value.  But I
have always appreciated the very well thought-out design of the Sun machines
and the overall excellent package of solid hardware, very stable OS, and
excellent customer service that Sun provides.

Some capabilities of the Sun -- which might or might not exist on the Dell
(I don't know) -- are the ability to partition the machine into "domains"
and dynamically move resources between the domains.  The Sun will run OK
with a bad memory module or bad CPU's.  As long as the Sun has one working
CPU, it will run.  I haven't done sys admin work for a while, but in the
past, Sun provided a utility called Symon that displayed a detailed picture
of the system boards and, if there was a problem with a component, would
show you which component had failed.  Whether these features are of any
value to you depends on you.  One other point in favor of the Sun is that
Sun is excellent at maintaining backward compatibility in releases of its
OS.  You could, in fact, take a ten year old Sparc IPC, install Solaris on
it, and use it as a web server or file server.  Almost every old (in
computer terms) Sun shop has those old "lunch box" (not pizza boxes) Sun's
hanging around, still perfectly usable.  Something I doubt could be said
about a 10 year old Intel box.

As I have mentioned in a previous post, the SunSolve CD is an excellent
resource.  One is tempted say "worth its weight in gold", but it is actually
worth more than that.

As far as the preoccupation with which box can produce the best benchmark:
In my personal philosophy, either a box is fast enough to run the
application for which it is intended, or it is not.  After that point those
less tangible qualities, such as those listed about, do count and should be
considered.
