Cool,
Do anyone have an idea if gcc4.1 is going to affect Fedora overall
performance at all or in either good/bad ways?
one thing that will be good is that this version of gcc automatically
detects that variables are never written to, and puts then in a special
ELF section; the result is that shared libs and binaries share that
memory between them instead of one for each app, and the total memory
usage of fedora will go down a bit as a result!
