Things you can't or shouldn't optimize: LFS: binutils, gcc, grub, optimizing toolchain is useless BLFS: gtk2, mplayer And I don't use java so I don't know.
Most of the time if something can't be optimized it contains ugly old style C code or something. -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
