Hello,
I decided to rewrite my old C++ application in full Objective-C.
This application used extensively arrays of double values and makes
many computations.
I decided to replace all my arrays by NSMutableArray and all becomes
very slow.
The sequence execution between the C++ and Objective-C is the same
(executing the code in debug mode, step by step), so i can
think there is no dead code.
The mutable arrays can contain between 1 and 3 double value objects
only but
my programm makes lots of such thing :
double aValueToCompute = [[myArray objectAtIndex:index] doubleValue] *
[[theSecondArray objectAtIndex:index] doubleValue];
Is there somewhere a topic about NSMutableArray performances ?
Should i stay with simple C array ?
Thx.
K.
