Crushing Lag during Reichs fight

I'd been having a pretty rough time on the Dr. K Taskforce. The lag was intolerable and was causing my commands not to. go off. I rebooted my machine, my cable modem, my desktop switch, and made sure nothing unnecessary was running on my PC before logging back in.

The lag is still not great, but I'm at least able to get all my powers to go off. Until the fight with Reichsman, that is. During the Reichs fight itself, the lag became completely crushing again. Powers didn't go off. My character couldn't move around a lot. All the other players, Reichs, and the AVs rubberbanded around. It was miserable.

Then when Reichs was defeated, my dropped-packet-o-graph went back from looking like the toothbrush of a really sick person to looking a hair more normal, if still pretty lousy.

CoH is running pretty much by itself when I took this screenshot. I don't have anything else running soaking up ram or network resources. My router (with the wireless radio shut off) indicates no other devices attached, nor any odd incoming noise like portscans or DOS attempts.

Thoughts?
