Guys, i'm troubleshooting the slow send speed of a realtek NIC on a tiny cube pc (will post a mini review later). I have discovered that the NIC only works at full speed when the cpu is being stressed. Like, only when the cpu speed is high. iperf3 does not seem to put the cpu on high speed. Some power save event going on here.
Like, even pings get lower when the cpu speed is high. I have set " pcie_aspm=off pcie_port_pm=off" on GRUB, no effect. Still shows "ASPM L1 Enabled". Am i missing something obvious?
EDIT: I disabled intel's management driver. acpi-cpufreq took over. Speeds good now. My power meter doesn't measure such low wattages, but looking at sensors temperature values (40-41 ºC idle) , i don't think power has increased.
Solution:
- intel_pstate=disable on grub's config file.
- /etc/sysconfig/cpupower with ondemand on both lines
- cpupower service enabled
I think this might fix other slow stuff as intel's management is kind of conservative.
