Silence your heretic anti-Debian libels! ;-) Comparing them to
Gentoo,
indeed...
There is a Debian AMD64 / EM64T port, which will become official with
the next
release (insert compulsory "some time in 2010" joke here).
Sorry for being unclear; I'm not talking about x86-64. AFAIK it is
always a performance win to use 64-bit binaries on x86-64 because
32-bit x86 is so bad.
This is not at all the case with 64-bit PowerPC: it is usually a
performance loss to simply recompile 32-bit binaries as 64-bit.
Accordingly, only some initially misguided PowerPC distributions are
100% 64-bit.
