Very hard to say, you will be able to run more processes at once but
they will run slower. It really depends on whether or not you will
notice the slow down in a single thread or not. Probably your best
bet would be to suck it and see, if it is perceptibly slower just
reboot to a uniprocessor kernel.
i noticed about a 30% slowdown with the cache disabled... so 2 cpus
might be faster if both are running...
