Is "nic 100%" normal? RT-N66U with Merlin firmware

[ScubaCat]

It could be all in my head, but it seems like this router gets slower after it's been up a while. I switched from stock to Merlin firmware a few weeks ago and it seems better but sometimes it feels like it gets stuck a little every so often.

Is it normal to see 98-100% under "nic" when looking at the output from TOP? (Has this already been discussed? I couldn't find anything on it anywhere.)

Thanks!

The labels follow the values.....

0.0% usr
0.1% sys
0.0% nic
99.0% idle
0.0% io
0.1% irq
0.5% sirq

D'oh! Thanks for showing me what I should have already known.

I will now go hide somewhere in embarrassment.

No need to do that. My first response was to say....wow, maybe he found something we can go after.....took me a while to look at it.

Not sure why they did the display that way....it is a little bit out of the norm.

I think it has to do with Linux 'niceness'.

"man nice"
