As the cache gets larger it riches a natural plateau, in my initial tests this was at the current gui limit (4gb entries), I was looking at Ingo's results just yesterday and there was little (or no) improvement above 2^15 entries. The settings and position types will be a factor. It's quite easy to try out, just use the "set cache" command, you need to enter the number of entries in powers of 2 though, so the current maximum (2^22) would be: set cache 4194304 just times this by 2 to increase the cache (obviously this doubles the memory usage as well). I'd be interested in your results as it might be worth changing the minimum/maximum and default settings displayed in the gui.
