20 sec is not that long of a time. if you run 2.51, how long does it take to start? in 2.51 do you have any of these 3 problems? have you changed anything on your system? did the long loading and freezing start the first time you ran 2.53? what OS?
how many total torrents are loaded?
how many running (seeding and downloading) torrents?
how many channels are loaded?
in those channels, are there a lot of shared files?
how many RSS feeds?
in those feeds, are there a lot of items in your 'published items' tab?
any IP filtering, and/or scheduled tasks?
when you add a single magnet link it freezes? if you add multiple magnet links does it freeze longer? how are you adding the magnet link?
for your 'file too large' issue:
i don't think there is any limit to file size. it sounds more like the program is seeing a similar/same file or similar/same file name and getting confused.
in the files tab, is it the main file or a small txt file that is failing (is orange)?
do you have 2 of the same file going into the same folder?
