I was playing with gnumeric's help and I saw that it took 1.5 minutes to open in my 2.66GHz and 512 MB of RAM computer. I searched about Yelp speed problems and founded that you can pre-generate the help files with "yeld-pregenerate". Now it takes only 1 second to open that manual. Is it possible to pre-generate the help files of all gnome's applications?
