Maybe it is time to write down some guidelines that you should keep in mind while working with SharePoint 2007, or you could just ignore them as well. I found these guidelines in Blogs, articles on the internet but I wanted to group them together.
| | Limit |
| # site collections in a web application | 50.000 |
| # sites in a site collection | 250.000 |
| # subsites nested in a site | 2000 |
| # lists | 2000 |
| # items in a list | 10.000.000 |
| # documents in library | 2.000.000 |
| # documents in folder | 2000 |
| # documents in index | 50.000.000 |
| Maximum document file size | 2 GB |
| # search scopes | 1000 |
| # user profiles | 5.000.000 |
These guidelines are not hard limits, meaning if you have 2005 lists on a site, your site will still work. The only thing that could happen by adding more items is that your performance could decrease.
