It's always the flow cpu that spikes up

Leslie,
please issue the "get perf cpu all detail" command to see if which CPU
is going up. I suspect you're hitting an ALG or this is going to CPU for
some odd reason.

I'm having a strange problem that I haven't been able to fix after
much studying --
Basically my setup is host 1 - fw1 - dedicated 1gige link (~25ms
lag) - router2 - fw2 - host 2
I can blast udp across this pipe without a problem, but tcp traffic
seems to be limited to about 3 mbyte/s -- I can make multiple
sessions that are all transferring at this speed, but no individual
session will go over that "limit"
Another thing that makes me extremely suspicious is occasionally
when I start a transfer I'll see a brief cpu spike -- like shown below
get perf cpu detail

I've obviously spent hours and hours on the phone/email with tac
without much help. Does anyone have any ideas of what could be
doing this? Any troubleshooting tips?
Thank you
Leslie
