Refer to my earlier posting on the cache architecture: if you have an 8
MB memory expansion card installed in the IIgs, 32 KB cache will cause a
speed penalty, as the memory above the 7 MB mark is not cached.

The IIgs likes to place some non-relocatable data at the top of memory,
but I don't know how often it is accessed and therefore whether this
speed penatly will be significant.  The RAM disk would also occupy this
area (if you were using it).
