It isn't possible. Look for the fastest CPUs, not the highest number of cores, and run a uniprocessor kernel. I'm not sure if they're valid, but I've read suggestions that amd64 CPUs may be better for this type of workload due to the larger L1 (not L2) cache. If you feel like testing, compare i386 and amd64 kernels and post the results, there are people who would be interested to know... If you currently run a pre-4.2 OS, upgrade it, you should see improved performance just by doing this.
