My experience with i386 was that the zfs ARC code caused significant  
kmem fragmentation.  While I have not tested this with recent commits,  
I haven't seen anything that would lead me to believe its fixed  
either.  I seem to recall Kip said he was working on UMA changes or  
something like that to address the problem.
