ZipGS strange slow-down

[spec@vax2.concordia.ca (Mitchell Spector)]

   I found this rather odd, with my ZipGS active (set to highest speed)
I watched the animated introduction for Silpheed. Once it finished, I
quit and loaded it a second time, but it ran noticably _slower_. I tried
again and again, it continues to go much slower than it did the first 
time. If power-down the IIgs, then launch the game, the intro returns
to the speed it should, although the above repeats itself where loading
it a second time slows it considerably.

   My guess is the cache is not getting flushed, powering down the GS
of course clears whatever was in there. Still, I find this occurance
rather unusual. Is this _normal_ or is it just some oddity caused by
Silpheed? I'm using a 15/64 ZipGS btw (I doubt this is another problem
caused by a weak powersupply, though in any case that will be fixed
in a matter of days).
