@stephenw10 But actually, is it normally in case of working suricata, crowdsec and traffic shaping limiters (up to 95% of max capacity in Limiters) my ISP speed going down to 60%/70% of max capacity ( 1GB Up/Down)?

stephenw10

No.
However what is seemingly quite common with those N100/N200 CPUs is the speed/power values passed by the BIOS result in slow running. Check the CPU frequency reported during the test.

@stephenw10 during speed test result:
Intel(R) N100
Current: 2922 MHz, Max: 806 MHz
4 CPUs: 1 package(s) x 4 core(s)

Core-level control is the best practice in most cases, especially for hardware with only a single physical CPU. Changing this setting requires a reboot.

Mmm, OK. That seems good.
I'd also try runing top -HaSP whist testing to see the per core CPU load at the time.

You have SpeedShift enabled?

Be good to see more of that top output so we know what's generating that CPU load.

@stephenw10 Yes Speed Shift enabled

stephenw10

Ok so all Suricata load basically. If you disable it as a test without any other changes do you get full bandwidth?

Antibiotic

@stephenw10 Yes, exactly, if suricata disabled speed test show as should be about 95% of max capacity as set in traffic shaping limiters!

stephenw10

Hmm. Do you see the same in legacy and in-line mode?

Antibiotic

@stephenw10 Use in-line mode, don't use legacy mode. Do you want to test in legacy mode?

stephenw10

Yes, test legacy mode. See if there is any change.

Antibiotic

@stephenw10 In legacy mode looks like speed as should be

stephenw10

Hmm, so possibly some netmap issue. If you run sysctl dev.netmap.admode=1 it should prevent netmap running in emulated mode which is very slow. However that does mean it can only run in native mode so may break if that's not possible for some reason.

Antibiotic

@stephenw10 I will try to set in native mode, but also have net.bpf.zerocopy_enable=1 is it not a problem?
