Hello,
So I have this big, performance critical function that takes
about 9 seconds to execute. If I add :
double[] direct = new double[2];
... at the beggining of the function, with no further
reference to this array, suddenly it takes only 8 seconds.
Any rational explaination to this? ( Seems unrelated to
garbage collection )
Which compiler? Which compiler flags? how are you benchmarking
it?
dmd 2.065 , -O and using std.datetime.StopWatch before and after
function call.
I tried to narrow down the "problem" but doesn't look easy.
I guess never mind that.
