I'm surprised there isn't anything on the web about this. I just searched google and altavista (remember them?) but came up with nothing. In any case, loading shared libraries is slow. Compiling everything statically would be much faster, but you'd sacrifice huge amounts of disk space. Preloading helps to work around the performance hit you take when using dynamically loaded libraries by getting ld.so to load the libraries prior to runtime, so it doesn't have to work as hard when you're actually running the program. It might be interesting to see a side by side comparison of something big like mozilla or gnumeric with and without preloading. I suppose if such a thing already existed we'd have found it in our web searches... noah -- _______________________________________________________ | Web: http://web.morgul.net/~frodo/ | PGP Public Key: http://web.morgul.net/~frodo/mail.html
