Hi Andy,

This bit of the discussion is with the standard node tree setup. I think were all agreed that having one million objects sitting under a single node will not work. Spreading the object load to other nodes may help but i doubt it.

We would like to understand better what the impact is on the rest of the system. If, say, we had a million objects sitting in a folder which is never visited, and all lookups to objects are by using an explicit id, will the system perform well?

eZ 3 isnt quite ready to decouple as you suggest. However, eZ 4 will be. eZ components have part of the framework necessary for this, so for eZ publish 4 a variety of storage strategies may be implemented. Though im sure only the node tree will be available at first.

Thanks for that, Paul, 'preciate the clarification.

Ah, understood. That'll be valuable information and I'm looking
forward to it. It's absolutely pertinent to the site I'm now developing.

Oh?! That sounds very promising. Is there a delivery window yet
for eZ 4? I'll be starting a project about mid-summer that will require
some of the things I've mentioned in this thread. If possible I'd like to
plop an establised CMS mechanism "on top" to handle design and such,
rather than build everything from scratch. eZ of course would be first
choice if it had the capability. But I'm worried about limiting the growth of
the product, just becuase I was after a quick and dirty first launch.

Hi Andrew

The perfomance testing mentioned here is by using the convetial content tree.When the data is generated we'll see how it affects content at other locations in the content tree.

As Paul mentions, it's not possible to have "loose objects" in eZ publish 3.x. The modifications required are however feasable, and we'll probably have support for it in the 3.x series before the 4.x series. As mentioned before, support ( http://ez.no/services/support ) is the right channel to get this implementet, and into the next eZ publish release.

<i>Hi Tony

I'm setting up a test system now with 1000000 users in 1 location, and 500000 users in another location. I'll be gone the next week, but when I'm back in week 9, I'll probably have some performance numbers.</i>

Hi Kåre,

Something new about these performance numbers?
