IIRC, the ARC is limit to 3/4 of total memory. That is the max, it may 
use [much] less, depending on overall memory use.

In your case, where you are allowing up to 90%, the ARC may get small if 
that memory is actually getting used. zfs-discuss is a good place to get 
info regarding ARC vs VM memory
