I solved both the two issues 

-----------------------------------------
Test passed with the SEC2 Driver.
0.07user 0.35system 0:00.86elapsed 50%CPU (0avgtext+0avgdata 785664maxresident)k
0inputs+0outputs (3091major+0minor)pagefaults 0swaps
-----------------------------------------

I also discovered that on cygwin-1.7 the 
--with-pthread option is working with half of 
the CPU usage than before.

Regards
Marco
