Most of those processes are used by the kernel, some of them, if you
aren't using the specific hardware or functionality they provide (such
as USB or ktrace) can be disabled by compiling your own kernel (see
here: http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/kernelconfig.html).
 While this may not provide a *HUGE* performance increase, it may be a
good idea to try.  I would also recommend, perhaps, adding some more
RAM?  :-)
