Speed Up PLAXIS Cross Section Curve Export


I am currently working on a dynamic modelling project in PLAXIS where we are obtaining the lateral earth pressures on a gravity retaining wall.

The retaining wall is modelled as a linear elastic material. 

To export the results, I have preselected nodes and stresspoints in the vicinity of the wall-backfill. I then draw a cross-section near the back of the wall and export the results for ~2000 stored steps to see the variation in earth pressure against time. 

The result export ends up taking longer than the analysis itself. Each time-history requires roughly 3 hours of analysis whereas just generating the curves can take up to 12 hours.

Is there any way to speed up this process?
