Would a document with 10,000 pages be allowed?
Would a document that large cause problems in any of the interfaces?
The maximum number of pages in a document is (2 ^ 31) -1, which comes to around 2 billion pages. https://support.laserfiche.com/kb/1012452
One reason we use TIF as the document format is that TIF documents (unlike electronic documents like PDFs) can be served to clients piece-meal. So there shouldn't be any problems for the client programs. If users try to export the entire document then it can take some time, but other than that things should be fine.
We've got some 25,000 page documents as the result of an import. The client seems to handle them without any issues. As Ege mentions, the client only tries to load the images that scroll within view on demand. The only slowdown was when I tried to do a search with the document open (CTRL + F). It appears to do a scan of the text and consequently takes quite a bit longer.
