This is long known.. I thought this was because elf-shared libraries were somewhat slower, but that cannot account for 50%...
The mapping for elf is more complicated (isn't it?), but this, too, should not account for 50%...
I doubt that gcc -S will help... gcc's output is not significant different when using a.out (unless you use -fpic also).
Any ideas? I'd like to have an answer to this question.. back in the i486 days, the difference was about 10%, and nobody cared... but 50% (66% in that case) is way to much!
