So... take 1GB system, run your favourite benchmark. Then reserve 512MB for tmem, rerun your benchmark, then run the system with 512MB/512MB swap, rerun the benchmark?
Tune the sizes so that first to last run differ by 100% or so, and see how much first and second differs? If it is in 1% range, you are probably doing good...?
