[Zope] ZOPE VS. PHP, VIGNETTE ETC.

[Ben White]

Hi,

I am new to Zope -- really excited about it -- but have a few basic 
questions (which I'm sure have been asked before).

1. HOW WELL DOES ZOPE SCALE?
Is anybody out there using this for high traffic sites? We have been 
using a custom blend of PHP and Mysql for a busy site and it works 
pretty well (although MySQL seems to choke when we get really 
slammed). How well does Zope scale?

2. HOW FAST IS ZOPE? VS PHP?
And how does it compare to the PHP/MySQL combo? Are their any 
benchmarks available?  It seems pretty quick but I'm not sure what 
type of transactions are going on below the surface of the pages I'm 
looking at.

3. HOW WELL DOES ZOPE WORK WITH MYSQL?
We have built some pretty serious backend with PHP and MySQL and I'd 
love to be able to keep our database structure etc.

4. HAS ANYBODY COMPARED ZOPE WITH VIGNETTE?
Some of our big clients have considered using Vignette. Seems Zope 
has largely the same mission -- albeit with a lot of catch up to do. 
Has anybody made a similiar comparison -- and if so do you have any 
info or ideas to share?

4. MIGRATING
What is the best way to migrate from a traditional web structure to 
Zope? For instance do you have to rebuild and register all of your 
objects with Zope through the web interface? Or can you upload files 
and have them be recognized by Zope?


Thanks for the help

Ben
