routerboard 112 cpu load?

hello there,

i have for an 7 km link the rb112 in use with on each side an directional antenna. - i am a bit afraid because i see when no traffic flows
a cpu of 60%?


the configuration:
both sides as a bridge with nstreme enabled. (band 5.7 GHz)

any idea why the cpu without traffic is so high?

thanks!

chris

I use many RB112s, but not nstream. How are you looking at the cpu? Just connecting with WinBox will drive the cpu up. These boards don’t have a lot of power but they also don’t seem to care.

As an example some of my CPEs have a script for measuring signal; converting it to an LED indication. That script alone will spike the cpu to >90% but doesn’t affect throughput.

hey,

yes, this is correct, tried 2 ways, first one via winbox, senond via ssh,
shows the same result..

running with bandwith (fixed) 18mbit so i can transfer 1.8 mb/sec.
(just a not hard test)

may you are right, that the router don´t care about it.

when i transfer !NOT the highest possible bitrate via the line the RTT
rises up plus 5 ms… - but think this is an other issue… (router does not handle icmp on the highest priority :slight_smile:

thanks for your response..

chris

p.s.: btw, i have posted yesterday previously a message.. may you have an idea for me?

(bad signal on RB532 with 2 x R52 (omni + direc ant)

is polling turned on?

that uses quite a bit of CPU just sitting idle, but at the same time the load does not seem to increase much beyond the idle rate even when pushing 10+mbps through the link.

try turning off polling, but I suspect you will get better performance with it on, despite the high idle CPU usage.
