Hello Uwe, Very well, it seems that we are on the right track. So you might gain some speed by preventing some minor modes to load at the beginning and load only when you need them.
Like Ihor Radchenko mentioned in his previous a great way to diagnose the issu would be the following: 1. M-x profiler-start cpu 2. open your file 3. M-x profiler-report It will let you see which functions are slowing you down. HTH, -- Jeremie Juste
