Before changing a number of calls to vForce.h functions, I ran a few test cases to assess potential execution
time improvements; the results are disappointing.
Comparing the time to run vvsqrt( ) on a 10000 point data file to a simple for( ) loop (i.e., for( ii=0; ii<10000; ii++ )
yy[ii] = sqrt[ii] ) shows a slight improvement ( ~236 vice ~243 microsec),
whereas comparing vvsin to a simple loop actually shows slower performance (~395 vice ~213 microsec).
(FYI, test was run under OS X 10.6.8 on a Dual-Core, 3 GHz Xeon processor.)
Is this performance typical? I'd really like to speed things up if possible.
