In case anyone is curious....I just tried this.  My check of how slow
the machine was was a user level program that did

	while (! signaled)
	 { count ++;
	 }

and asked for a SIGALRM in ten seconds.  Then the speed measure is how
far count gets.  With the cache turned off it counted only half as far
(plus or minus maybe 10%) as with the cache on.

This was a 750 running MtXinu 4.3+NFS.
