How big is the cache?

[J. Porter Clark]

Is there a way to find out how big the disk buffer cache is in SunOS 4.1?
I'm talking about the thing that gets flushed out during a sync().  I used
to know how to find out back when I was working with an old System V
release 1 machine, but SunOS looks pretty different (maybe it's not a
constant?), and I don't remember anyway.  (I don't have source, by the
way.)
