[amibroker] Re: profiler checks and finds cci function most offending

["murthysuresh" <money@xxxxxxxxxxxxxx>]

the default. here is the timings that i am seeing


start=GetPerformanceCounter(); 
CCIVAL=CCI(14);
finish=GetPerformanceCounter(); 
printf( "lapsedtime in ms = %g ", abs(finish-start) );


i am getting 505 ms. does not add up for me. what else can i look at 
to trouble shoot it.
