With "-xtarget=ultra" the reload times are still the same,
but the scan times seems to be better (I have no exact numbers).
I tried a 64bit-build with "-xarch=v9 -xcode=pic13", but
then 'make check' failed.
I have no further ideas yet and I'll change the hardware to
some newer CPU's anyway. So I stop it for now.
Thanks,
Martin
