How much bandwidth are you using there, I am only barely using 110-130Mbits average.
Im thinking it hasnt reached a 'threshold' to fire up more links.
The filer is quite busy at the moment:

Usually, it's about:

(100 Mb/s ~= 12,200 Kb/s, neglecting packet overhead)
So, most of the time we are well under even a single 100 Mb/s pipe, and are getting some data on all the trunks, just imbalanced. I have seen it peak above 12,200 Kb/s in and out, so even though it's overspeced 95% of the time, we do take advantage of the trunking. The filer is connected to a Cisco WS-X5225R card in a Cat5000 on the other end, if that helps.
What I need desperately is more cache. We had this sucka pegged this morning:
