EPiServer gives our users a tremendous amount of power and flexibility. However users can occasionally do things that may affect performance or their experience of EPiServer. One of these things is adding a large number of images/documents into a folder in the media library. By adding too many items to a folder the folder not only becomes cumbersome to browse and use but can also affect performance in extreme circumstances.
Recently I spoke to a client who had recently migrated to EPiServer from another CMS. They'd noticed that the number of internal broken links was going up rather than down after the migration. I thought that this was strange as EPiServer maintains all internal links by reference so if a page is moved in the page tree then it's link is automatically updated.
