	Perhaps the confusion about what cache we are taliking 
	about is my fault, seems to be. I apologize.

	It is the "optional turbo cache module," as from my Zeos manual.
	It is commonly refered to as the "external cpu cache," as opposed 
	to the internal 8K cpu cache, and comes in numbers such as 
	256K, 128K, and some machines use 64K.

	I think I've seen 3 respones as to my question about what 
	speed increase could be expected by using the cache:

		a) %10	
		b) not telling (the zeos guy)
		c) %80

	The reason I'm so interested in the performance increase 
	is because I am using a hacked XFree_2.0 mono sever in Linux.
	The problem is that although XFree is generally a fast X-Server,
	XFree does not support the Viper, due to Diamond's policies.
	So, some of us Viper users have hacked the mono server to get 
	it to work.  But it is not very fast.  

	I thought I might throw a cache at the problem.   And if the 
	performance increase is in fact going to be %80, then it might 
	be worth the trouble.  But, slow+(.10*slow)=(still slow).  And
	that's not worth the $200 price.
 
	

	Thanks,

	Steve Whitlatch
