I have been running Postgres on an SMP MIPS machine for quite
a while. I haven't been trying to make it work hard so I can
only attest to the fact that it runs without fault. So yes,
leave the hyperthreading enabled and enjoy.

One of my colleagues has been doing some experiments. It seems
that the code generated by the Intel compilers is a bit faster
than gcc.
