Is the NetBSD method of buffering better or worse than SunOS? (I'd
suspect better since NetBSD is supposed to be "better" than SunOS in terms
of performance). I am familiar with the caching scheme in Linux in which (I
believe) it's managed like SunOS. Is this correct?
I thought being able to utilize all "free" RAM as a cache would be
beneficial to performance.
Please don't flame me if any of the above is nonsense, I do not know
ANYTHING about the inner workings of an operating system on any platform.
I'm just a dumb user who sees that performance is pretty bad on my system :-)
