A large buffer with no text paragraph anywhere in sight caused Emacs
to search back for the end of the previous paragraph, in order to
decide what is the base direction for the current paragraph. In
addition, every line is long, but empty, so regex search also takes
time. The search is limited to a certain number of lines, so the
lag should level out after that, but otherwise just don't use such
empty lines in buffers whose bidi-paragraph-direction is nil.
