I'm not seeing anything obviously wrong here. As a note, FixedArray tends to be slightly faster than LinkedList, but that's a matter of a few percent.

can you enable impstats and see if it reports anything interesting about this?

 I found omfwd would discard msg if I pass more than 1000msg per second.


more information about this please, I've passed 400K messages/sec with
omfwd with no loss (at which point I hit the limit of gig-E), others have
done more with faster networks.

What does your config look like?

 So
I need to use mmsequence to split intto several omfwd queues.

While the input modules can process lots more message than omfwd, and I
found the imudp/imptcp use epoll, is there any output module using epoll?


epoll is a way to look for incoming things, it's not useful for outbound
stuff
