One needs to treat any test which involves networking to localhost with caution. They tend to show large (+/- 10% or more) swings in throughput from one run to the next. Some sort of cache associativity thing; not sure.
Running the test between separate machines is much, much more repeatable.
We'll get the cpu-local hot pages list code going soon; that may provide some benefit to this sort of thing. Even on uniprocessor. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
