Slow loading/saving of files

I'm just curious if what I am experiencing is normal and I need to get used to it or if there is something I can do to speed things up.

I have a .mph file with the solutions of a parametric sweep (RF frequency domain study...15 frequencies with 4
different values for the parameter that I am varying). The file is about 4GB.


What I want to do is access the file via the Livelink for MATLAB and post process the data.

It takes several minutes (5-10) to load the file. I'm using the Livelink for MATLAB and when I try to export the model file to the server it automatically saves even if I have changed nothing. This takes even longer 10+ minutes.

All in all it takes 20+ minutes before I can access the data in MATLAB. Is this normal?
