Hi, It is normal that Netmap is verbose. However, the current implementation is not efficient at all and was tested only with an old version of Netmap. There is a pending pull request (#225 ) that makes it a little better (zero copy support at least), or you can use FastClick's one. DPDK support is much more up-to-date, if you're not particularly stuck with Netmap.

Thanks tom for clarifying on this. As i have got an "rcu_sched self-detected stall on CPU" while running FromDevice in 2 simultaneous threads using netmap devices.
I am currently not looking for the DPDK option.
Ouch, that basically means Netmap blocked one CPU core... That happens when you misbehave with the Netmap API. Can you try the pull-request version?
Will run with the patch and share the result.
Thanks
Hi, The patch work well for me, from last 3 days click with the patch running fine, and it also suppresses the above mentioned logs.
Thanks @tbarbette .
