Inlining functions results in bigger code, which can lead to more cache misses, especially on processors with small caches like the celeron. I've seen some article where the author compared the speed of Gentoo versus Debian and Mandrake. He's compiling all programs on Gentoo with -O3 (inlining a lot of functions) on his celeron and then compares the speed with Debian and Mandrake and it is never the fastest. Seems to be that the original article is removed from the web, but google cache still has it: http://216.239.41.104/search?q=cache:Ba3cFknoo4sJ:linuxfr.org/redirect/27426.html+%22many+people+recommend+-O3+for+this+kind+of+Celeron%22&hl=en You can't be certain that inling is always faster, it depends on too many factors.
