It probably would be interesting, but I'd think an Intel employee would be
the last person to post something like that to a public list, unless it

I did some benchmarks on a kernel build awhile back, and "make -j4
bzImage" was about 20% faster with HT turned on; I believe this was a
linux 2.4.18 kernel.
