At this rate, that does indeed look like the indexer/catalog looping like crazy on one/multiple books.

The usual, 'dumb' way to check is to search for a nonsense string from the Homepage, and see if anything shows up as 'Currently Indexing' (or whatever the header is actually called, can't remember OTOH).

The sensible way to check is to look at the output of htop, and check if the indexing thread is being silly. Checking the logs (showlog in a shell, ;dm in the search bar) is also generally a good idea.

As for the amount of books, yeah, I wouldn't go over 500 items, 1K at most, besides being a nightmare to navigate, it pretty much destroys the Homepage perf, and makes the boot/resume process churn forever when it checks the integrity of the catalog. (On the bright side: FW 5.x does much better in that respect than previous iterations of the software, and the better CPU of the PW2 is a tremendous help too. My old K3 w/ ~1K items is amazingly funny to watch over htop as it boots/wakes up...).
