I am running BSD2.0 & when I bootup the machine, Unix automatically
takes 10% of my available RAM (in my case 96megs of total RAM) & uses
this 10% for the disk-cache (9.6 megs are used for our disk-cache) ...

Is this standard in Unix that the system allocates 10% of total RAM
for the disk-cache and if so, what file do I need to modify so that I
can alter this setting?
 
When I run TOP, it tells me that the server never has less than 55megs
of available (Free) RAM ... so I'm thinking of using this unused
memory to increase the disk cache.

ANY SUGGESTION?  Thanks
