On a 2GHz AMD64x2 machine it took 118minutes of CPU, basically 100% of one processor for 2 hours to obey M-x rmail-mode after I had loaded the file with M-x find-file-literally. This seems in line with my belief that the algorithm being used is n^2, and for my 95Kb file is totally unacceptable. The good news is that it does run....... eventually. On my laptop this translates to over 3hrs which is comparable with the time between getting up and going to work, or being at work. I am willing to help but I do not understand what it is trying to do; but it is reading data more than once. ==John ffitch
