Does MS have any plan to support the x32 memory model? It needs kernel
as well as compiler support.
Could a shim layer possibly bring x32 to a x64 process under Windows ?
Or else have most of the code handle memory as "offset inside a bucket",
and reduce most pointer to the 32 bits offset.
It would be good to precisely measure what slows down 64 bits with side
by side performance comparison using hardware performance counters like
the one oprofile under Linux has access to, that can count the number of
cache miss, branch mis-prediction, and the like. It can give a very
precise idea of how efficiently the CPU runs.
BTW the last time I had Seamonkey use all the 32-bits adress space, the
result was *really* bad. A system down to it's knees, and not able to
close the Seamonkey process anymore. It's harder to get the same thing
with Firefox, the lazy tab opening helps :-)
