XO-1(.75)

I'm using the XO-1.75 a bit more these days and gives me a sense of XO-1 performance wise.
So I compared my (500/200 overclocked) XO-1 running F14/os885/Sugar-0.94 to XO-1.75 running F-18/13.2.0-11/Sugar-0.98.
XO-1.75 was significantly faster to boot (~20sec).
However, XO-1 was faster (to open)  clock, fototoon, ruler, distance, terminal, pippy, implode, log, paint, measure and write activities !!!
XO-1.75 was faster in the tam-tam suit, scratch and etoys, speak, calculate, turtle art, maze, moon, record and browse activities. Memorize was a toss.  
In all cases the difference  was 1-2 seconds either way.
I was wondering if some pattern could be recognized and hopefully improved or is just the different (presumably more resource demanding) acivity versions.
