UPDATE:
After several weeks of observation, I am sharing to you a few steps to obtain higher scores during speed tests here at tmn.
1) Do the canopy tweak and the 20 Steps.
2) Do the ipconfig /flushdns thing.
3) Run CCleaner to eliminate all crap.
4) Use Internet Explorer 7 in conducting the test (for me its better than other browsers for speed testing).
I discovered, I just don't know if its a bug, that there is a hidden download data of 749 kB in the download test section. Though usually appearing unexpectedly after running the 579 kB download data, it usually gives higher scores.
Hope you guys absorbed the inputs.
