So what the limit of ez (not only for the storage but for the number of object EZ could manage) How many users/objects (small object with 10 or less attributes and big object with 20 attributes) ez will manage?
I don't think I need to have millions of images to have a bug with the filesystem. Just try to list a directory when you have more than 10000 sub folders.
How do you manage your 50000 post? do you use special extension?
Just to clearify: eZ does not say that the limit of eZ publish is 250 000 objects.
The eZ publish 3.8 package was tested with 2 million objects and it worked fine.
The performance and number of objects is no an exact science though. It does depend on the design of the content architecture. If you e.g. have all the objects in the same folder you get performance issues with sorting when you have large amount of objects under one node. It does also depend on the structure of your content classes. Some setups are heavier than others. So, to know the limitations of your setup you need to test for this.
Our testing was done with the standard content class setup in eZ publish. We created folders with 5 000 articles in each folder using a 3 level hierarchy.
