QoS maxing out CPU

Networking Quality of Service
1

I own an IPFire Mini Appliance. Is the IPFire Mini Appliance CPU to slow for a Gigabit Connection? When checking with htop i notice that only one of the Cores is maxed out/being used. The Connection with QoS on is limited to about 17 mb/s. Any Chance to improve this?

Wilhelm.,

1Gbit/s could be doable but probably not realistic., there are a lot of factors that could throttle your speed.

What services are you running besides QoS? IPS, VPN etc…

The board can handle a Gigabit connection in one direction but only without any other features like QoS, Intrusion Detection. (also PPPoE encapsulation needs much CPU power)
so for a real (bidirectional) Gigabit connection it is to weak.

btw. please use correct captial letters for speed’s.

17mb/s stands for 17milibits/s which is unrealistic slow.

17Mb/s stands for 17Megabits/s which is still much to slow

17MB/s stans for 17MegaBytes/s which is slow but may be realistic if there are more features enabled than QoS. But at my last tests the APU2 which have the same CPU/Nic combination was still a bit faster.

I am sorry, of course i mean 17MB/s.
So it is normal that just 1 Core is used? The only running service is Location Block. What are my Options? Just configure QoS to use 12-15MB/s and disable QoS if i want to start a big download?

17MB/s corresponds to 136 Mbits/s

What services are you running?
