On modern hardware 2GB+ isn't really very big. Have you tried just reading it line-by-line with <F>? I don't know what your performance requirements are but most log-parsing jobs aren't terribly performance sensitive.

You might find that you don't have to tune your regex much once you switch to reading line-by-line. That's because each line will be much smaller than 8K, so the penalty for backtracking on a .* will be consequently much smaller.
