Same sort of problem here.

I can save a 4-D double array (initialized by zeros(k,l,m,n)) that ends up being 2612736000 bytes in about 1 minute. Then I try to save a structure with two fields--one field is a vector and another contains one or more .fit class objects--and it's only 184268260 bytes but takes literally hours and hours to save just a fraction of this struct variable and I end up killing the process because it takes longer to save the data than just generate it, even though it takes 3 hrs to generate it!

Why would this be the case? It makes little sense.
