This  means, the  released binaries  will  never be  compiled with  this
optimizations (since  they are  expected to  run on  all architectures).
And  that  means, people  doing  benchmarks  of  the  "out of  the  box"
installations, will find FreeBSD slower for "secure web-hosting".

Unless, of course, we provide different binaries on CDs.
