Hello,

We are seeking information on running Zope under an
extreme load. Here are the metrics of the system that
we would like to migrate:

# of users with an account:              40,000
# of R/O concurrent users at peak time:   5,000
# of R/W concurrent users at peak time:   5,000
# of (static) documents:		800,000

Read-only users mostly search and view documents.
Searching is currently done with metadata, but we
would like to add full-text search on text renditions
of the documents. Read-write users mostly view and
index documents.

--> Has someone already run Zope under such extreme
conditions?
--> Could someone share ideas on hardware and software
issues?

We plan to do some kind of feasibility testing. At
this time, here are a few of our ideas:

1. Run ZEO
2. Possibly add an additional layer of load-balancing
with specialized Linux software
3. Serve static pages with Apache or IIS
4. Do not rely on ZODB only  consider MySQL,
Postgres, Oracle
5. Consider alternatives to ZCatalog  for example
Lucene
6. Develop customization with Products instead of
ZClasses
7. Use Zope RAM caching as much as possible

Your opinion on this topic will be very much
appreciated.

Thanks,
Robert
