You are unlikely to find any help on this forum for DragonFly BSD. Please send an e-mail to users.AT.dragonflybsd.org. The group is minuscule (less than 10 developers with Matt committing 80% of the stuff) but they are very good at addressing issues. Most likely Matt himself will offer you some advises.
I am too tired to go carefully over your e-mail tonight but on the first glance temperature of little over 60C are within your CPU specification range. HAMMER is not a RAM hog like ZFS (which I run at work). I am running it on my home file server. Some interesting outputs for you
