Not using a firewall. I will try it with the settings file.
Also, it does seem related to the amount of media. The Movies section which contains much less items load much faster than the TV Shows section which contains many more items.
Logs attached (couldn't put on pastebin due to the size).
First there doesn't seem to actually be a log file attached :)
Second the line "couldn't put on pastebin due to the size" sets alarm bells ringing for me... You don't happen to have loglevel set to High do you. That would be the reason for the large log size and could also be the reason for the slow performance. Loglevel High absolutely kills performance, set it to Off and see if things are any better.
