My concern was relative performance changes, not absolute performance - at
least, not yet. We are, alas, some way from production.
The 1.2/1.3 argument is still going around the office. 1.2's fast enough
for what we're doing now, and gives us a consistent platform. 1.3 seems to
need to mature a bit on Unix platforms.

Either Orion or the client is in the foreground, with essentially the same
results, and no other applications are running. The tests have been run
the same way on the same platform all along - they're part of the "does it
still seem to work" check I try to run on every update.

I'd never consider Win98 for production. We're a Unix shop, and I've
admin'd assorted versions for around 20 years. We haven't made a final
production platform decision yet.
However, this machine is sitting on my desk so it's real handy for
development and testing. It needs to run some win32 applications, and has
some hardware that NT doesn't like.
One of Orion's strengths is being able to do useful development under this
pervasive but less than optimal OS.
We ran comparison benchmarks on several OSs, JVMs, and DBMSes, and will
continue to do so. This one's the quick and dirty test, and the 3x
increase in times finally needs to be investigated. I was hoping the
problem would go away with newer versions, but no such luck.
