Automated evaluation and data export takes a very long time

Hi, I'm trying to automatically read out simulation results from Plaxis. For this I have oriented myself to the following how-to (LINK). However, the evaluation takes a very long time, because each step is queried individually. If the whole process is done manually (Curve manager -> New -> Node displacement as X-Axis,  SumMstage as Y-Axis), then you are much faster. Why is the manual way so much faster than via a script? Is there any other way to get the desired output?
