The usual cut-off journal length is 2000 posts, however some members have experienced slow page loading before that point. As your own journal is >1500 posts, I think it's reasonable to start a new thread. Please follow the instructions here.

Note: there are other causes of slow page loading on our forum, including large numbers of "unlogged guest" activity, usually search bots . The webmaster recently upgraded Cloudflare security level, which can slow things a bit, but certainly not several minutes!
