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).
