RB333 CPU tanking out to 100%

I have a pair of RB333 with an SR5 card in each. I am running them in turbo mode and doing about 30down/10up mbit. I understand I am reaching the limit fo 802.11a in turbo but my cpu is also maxing out. I thought the RB333 should be able to handle several links at once via bonding or nstreme.

Am I asking too much? I would like to add second link for bonding or Nstreme2 as I am quickly running out of bandwdth.

I have connection tracking off, 100% routed. EVERYTHING is turned off that I can get away with. Just a simple routed link running Nstreme. I would turn off nstreme but that makes the link go seriously bad.

These radios also tend to have kernel panics from time to time and there is already a supout sent in.
