creating plots is extremely slow

Dear Forum,

creating simple line plots (with global scope) of model results is extremely slow.
For quite large model files (2-3 GB of size) it sometimes takes several hours for one simple plot on a machine with 4 GB RAM and 8 cores. COMSOL needs more time for creating the graphical output of the results than for solving the model.

Did anyone experience the same? Is there a way to accelerate graphical output?

Thanks for hints on this issue,
Juergen
