Each view has a separate cache DB.  So if each of these 40 views
really needs to cache a certain amount of data, a footprint of 2GB is
not a surprising situation, even with a 32MB of max-cache-size for
each view.

Unfortunately not, unless you can consolidate the caching views to a
small number of views.
