Hiya, can somebody inform me why the next code :
bundle important
/*
lengthy Add ( lengthy a, lengthy b ) {
return a + b ;
}
lengthy caller2 ( lengthy a, lengthy b ) {
return Add(a,b);
}
lengthy caller ( ) {
lengthy numAdd = 1 ;
lengthy i ;
for ( i = 1 ; i <= 10000000000 ; i++ ) {
numAdd = caller2 ( numAdd, i ) ;
}
return numAdd ;
}
*/
import "C"
import ( "fmt"; "time" )
func important ( ) {
var timeBefore = time.Now ( ) ;
///////////////////////////////
var checkNumber C.lengthy = C.caller( ) ;
//////////////////////////////
var timeAfter = time.Now ( ) ;
fmt.Println ( checkNumber ) ;
fmt.Println ( timeAfter.Sub(timeBefore) ) ;
}
Is so mush slower than :
bundle important
/*
lengthy caller ( ) {
lengthy Add ( lengthy a, lengthy b ) { // nested perform
return a + b ;
}
lengthy caller2 ( lengthy a, lengthy b ) { // nested perform
return Add(a,b);
}
lengthy numAdd = 1 ;
lengthy i ;
for ( i = 1 ; i <= 10000000000 ; i++ ) {
numAdd = caller2 ( numAdd, i ) ;
}
return numAdd ;
}
*/
import "C"
import ( "fmt"; "time" )
func important ( ) {
var timeBefore = time.Now ( ) ;
///////////////////////////////
var checkNumber C.lengthy = C.caller( ) ;
//////////////////////////////
var timeAfter = time.Now ( ) ;
fmt.Println ( checkNumber ) ;
fmt.Println ( timeAfter.Sub(timeBefore) ) ;
}
End result :
The primary : 32.184687445s
The second : 6.873829046s
Does nested C features case somewhat overhead in comparison with top-level features?
