RPI cluster performance related to network performance
I think i have solved it now. The problem was that in the example in the source they had:

8*3,50*16 and i was assuming (which is a very bad thing to do) that i should change everything except the 16, that it was a constant of sorts. Turns out, my RPI should have somewhere between 0 and 2 in the last multiple, alas it should be

4*1,2*x where x is somewhere between 0 and 2 (as my estimation) thus i have only to find out the actual number for X, and for some reason it seems hard to find it, one would have thought that the instructions per second or instructions per cycle would be documented for RPI.

bottom line, there was nothing wrong except for my thinking. sorry for this post, i should had read up a little bit more before i posted. I blame it on stress. 

EDIT: i forgot to give the source that helped me solve the problem, here it is:

and thx for the help!
