I did a quick check, and found some RFEs and associated bugs that look
related to the problem that you're seeing:
* ZFS should avoiding growing the ARC into trouble
http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6488341
* ZFS/ARC should cleanup more after itself
http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6424665
It sounds like the ARC is shrinking (since after multiple runs it's
faster) but it's not reacting quickly enough to the increase in memory
use.
