strategy tester calculation speed on different hw - page 2

Thank you Alexx,

unfortunately, this chart cannot be closed with ChartClose(ChartID()) nor ChartClose(0).
I will spend no more energy on this.

 

Just to inform those who are interested:
I didn't manage to speed up significantly testing on i7 compared to core 2. 
By reducing 8 threads to 4 threads, those 4 threads execute a little bit slower than 8 threads. This shows that the size of L3 cache is not the issue.

It seems that new generations of CPUs are not speeding up as much as you would expect.

Just checked this piece of code:

void OnTesterDeinit()
  {
//--- end optimization
   ChartClose(0);
  }

And it did close the chart at the end of optimization.

OK, i rechecked and ... you are right. It does close when either finished or interrupted (Stop), when there is at least 1 (one) successful pass.

It doesn't if all passes have failed during OnInit(). Unfortunately when i was checking, all passes were set to fail (intentionally), so that's why i reported it false. I always check before claiming something on forum.
