[Zope] Threading, dtml and performance?!

Well, okay then. I get it. However, since it takes only 80% of 1 second
to load the page, its difficult to access another page... LOL.
I've tried the reverse now. Pulling a page that does heavy SQL queries
and then refreshing the speeTest page a few times. Adding some time
fields, the page only takes .1 second more than before.
I also mention that I built my own mailing list app for our site, and it
has run against 8000 emails, and still services me or other users on the
site, even though the bulkmailer takes up to 30 minutes to run fully.
So I guess the result is the same. Solaris has something funny, whereas
Linux does not.
But as per my first message, I don't think this test works properly
because the second IN is never executed, so this dtml doesn't actually
do anything to the server that would distract it or load it down.....

The output of the DTML method isn't important, but if you ran it and it
took a while (> 5 seconds or so), but then at the same time it was
running, you visited a page in the mgmt interface and that operation
took .83 seconds, that's the number that's important.. that lets us know
that MP Linux systems aren't "freezing" like Solaris systems. However,
if you ran this method, and you couldn't do anything on the system until
it finished, there would be a problem.
