Most DEB and RPM files are compiled for the oldest, usually slowest,
architecture of an architecture family.  For the x86 family, the code in
DEB and RPM files may be 386 code which is optimal only for a 80386
CPU.  Gentoo compiles code that is optimal for the CPU it is being
installed on.  Thus compiling all code during an install as Gentoo does
can result in a huge performance advantage.
