Cache's are good, but on some CD titles they tell you turn it off or as low as you can. Currently my default setting is up around 8mb, with 256mb of RAM. What's the reasoning and benefits of disk cache? Editor of the printed word, Ministry of 68k Truths (mini6)

mac-man6, your 8MB sounds just about right. The recommendation I always see is to have 32k of disk cache for every 1MB of physical RAM. 32k times 256 equals 8MB, so you're right on target.Matt No rank Permanent 68k roommates:

so why do some CD's ask you to set it as low as you can. Would'nt a high cache setting be good removable media like that?Editor of the printed word, Ministry of 68k Truths (mini6)

I've never known it to matter much what size cache there is. It is likely a holdover from early days of CD-ROMs, when something about the software's operation slowed down, or low memory(like 4MB-8MB) affected performance when using a large cache. I wouldn't worry about it unless the CD gives a specific reason.Otaku, part-time
