I'm benchmarking NuFW on PowerPC 64 bits and I see that MPI is using 80 to
90% of the CPU during gnutls_handshake(). Here are the top 5 functions:
I dig into gnutls and gcrypt, and I see that there is no assembler version
of MPI (for ppc64). I also learned that MPI is based on old GMP release
- Can someone write assembler code for ppc64? It should be easy since GMP
prototypes look to be the same, and assembler code for ppc64 already exist
- Would it possible to use GMP in gcrypt?
- Why using MPI instead of GMP?
For GMP, download http://ftp.sunet.se/pub/gnu/gmp/gmp-4.2.1.tar.bz2 and
I see that a 32 bits mode exists, but I don't need it. The computer is
running in full 64 bits mode.
