[thelist] zope: a few questions

Yep. Saves on having to pack your DB for starters. Then there's certain FS
operations that are close to 2 orders of magnitude quicker than equivalent
operations on the ZODB. No to mention being able to do cool things like put
a PDF on your filesystem, pass it through XPDF, and have that produce a
plain-text digest that you then use for indexing your content.

We've handled CVS integration pretty well so far.

I'm currently experimenting with a way of presenting the *entire* Zope DB,
with any kind of object, as a file system device that you can traverse from
a command line as per any normal folder. It'll make source-control issues
in zope a thing of the past.

Hmm. I really ought to commit my tuning patches for ZServer and Medusa.

Yeah, and the sad thing is that Apache's performance is nothing special. Of
course, you'll never notice unless you get into high-volume traffic. Still,
for an application server, Zope's remarkably good at doing static pages,
especially with judicious use of the Accelerated HTTP Cache Manager and the
RAM Cache Manager. JBoss is about the only standalone app server that's
faster at static pages.
