I hope they’ll fix those performance issues fast, because even simple and basic sites don’t work due to those issues. According to their developers they are working on it, but sadly they don’t know how to fix it yet.

As for performance – yes, a big issue, but one they are fixing.

It seems like you haven’t tried to made realy “custom” groups of permission, because if you see the file uploading there is piece of code that allows only the admin to upload and nobody else. You call that security levels ?!

And the third one. Oh yes, well we’ve all heard about the US Democratic website that there is something to boast about. But seriously, have you experienced the feeling that it’s going to take a large traffic on it’s shoulders ? Because i visited it a couple of times and frankly speaking it was not only slow but also didn’t handle the capacity of users sometimes.

Secondly, the admin model is not a simple “admin/all users” model, but a “create your own security groups” model. It has many levels of security control – (e.g. non-publishing author, publisher only, etc) and it lets you get down to field-level permissions for different groups of users, as well as grouping them for newsletters, etc.

Thirdly – this may not be something that’s wrong, but it’s something that can probably be fixed – SilverStripe has excellent caching. It was used for the US Democratic party’s website during the 2008 election, so it can handle load for quite large and small websites very well. I don’t doubt you’re experiencing slowness, but it’s quite probably something to do with your specific configuration rather than a reflection of the package as a whole.
