Real Time vs Off-Line Execution Times

[mbuta]

Hi,

Can anyone explain why the execution times [for the same work space] are so much slower in real time vs off-line?

Thank you.

Real Time


Off-Line

I think the reason you see such a difference between your two examples is because you have invoked a reloadEFS() event 11 times in the off-line image. The total time required to process historical bars versus real time bars is less. Due to the 11 reloadEFS() calls and the fact that the off-line chart is not handling any real time streams the average should be much less.

In your real time example, try invoking 11 reloadEFS() events and see if the average goes down.

Jason,

Forget the reloadEFS().
Look at the execution times of MY efs: AllIOBOS.Test and AllIOBOS.TestMA. Those are way diferent. How can that be explained?

Thank you.

Hello Mihai,

If you are referring to the differences between the two chart images you posted (real time vs. off-line), I believe the reloadEFS() calls are the source for the differences.

If you are referring to the differences between the formulas within either of the chart examples, the differences are a combination of the code used by each formula and the order in which they are applied to your chart.
