Asus N3050I-C for OpenVPN (100MBIT WAN)



  • I just signed up with vpn and did my own testing and compared to this guy here. AES-NI does not work at all. It offers ZERO assist. Not one 1Mbs.

    I've proven it here. I have doubled my cpu power over my asus 87u and it doubled my speed but look at this other guy results. https://forum.pfsense.org/index.php?topic=139926.0

    What settings are you using?

    AES-NI will be accelerating almost every setting to some extent. To test it's effects accurately you will need to enable/disable it in the BIOS though.

    The Turbo mode is show as 1601MHz vs 1600MHz for non-turbo.

    Steve thanks for feedback. AES-NI is enabled as you can clearly see in screenshot of pfsense that it says it's active to yes it's active in bios and should work. Turbo i enabled last night in bios but that will never take effect as one would have to max out cpu to 100% for turbo to kick it. My cpu maxes out 50% in pfsense during encryption testing so it will never get there. But to your point it shows in pfsense as 1601 so turbo is enabled as well. Look

    I have chosen freebsd hardware acceleration in both vpn client and under networking in advanced options which boosted my Mbps by 10Mbps but i max out at 120Mbs now. It won't do more. It's all about

    CPU cycles from what i see. I commented on this more here. Let me know your thoughts if you want. I think CPU cycle rate needs to be 3Ghz for ideal setup. Those AMD APU A10 7800k are 4.0Ghz and

    are cheap enough but how to chose motherboard with 2 nics, ideally intel onces in mini itx form. I have 2 1gb realtek once and have no problem at all with them in pfsense like some suggest they do. They do their job.

    This thread is also right on the money but it's 2 yrs old now so not ideal hardware anymore. That last celeron is cheap but i can't seem to find nuc or motherboard in itx form for it. I think ideal would be AMD A10 APU. Low power and high cycle rate but not sure about mini itx motherboard with 2 nics and what case. Etc. Then again that AMD doesn't have AES-NI so when pfsense 2.5 comes out it will become obsolete without those instructions. So scratch AMD without AES-NI too. This is a quest.

    If you are seeing CPU usage at 50% overall then it's likely at least one of your 4 CPU cores is at 100%. To see the full break down of cpu usage across cores run at the command line:

    top -aSH
    

    If one core is at 100% it should be running in Turbo mode.

    Specifically which A10 CPU were you looking at? As far as I know most of those support AES instructions. AMD have been shipping processors that will be supported in 2.5 since 2010.

    Without seeing te exact settings you're running it's hard to comment further. It seems likely you should be able to see more bandwidth from that CPU though. In the thread you linked Pippom reports 160Mbps from that same CPU with higher encryption settings.
