Does it have to be a compilation, or visiting a file with the error messages, putting it in compilation-mode, then invoking next-error exhibits the same problem? If the latter, can you post an example file which could be used to reproduce this? Also, does the slow 1st time happen in "emacs -Q"? Thanks.
