PfSense hardware for home router - OpenVPN performance
-
There is no significant difference between client and server modes for OpenVPN. There may be a difference between encrypting and decrypting but that depends of which direction the majority of your traffic is going. It too though is not something I've seen as significant. You should be able to push 100Mbps+ with that I would expect. Let us know your results.

Hi guys, new to the pfSense world :)
I got a j3355b-itx coming in the mail this weekend, which I will be mainly using as VPN server for remote access.
From what I have seen, these speeds are as OpenVPN clients. Has anyone done any speed test as OpenVPN serer for remote access?
My current router tops at around 30Mbps (as vpn server), I'm hoping to achieve at least 150Mbps using the j3355b on gigabit connection.
From opening post:
Intel Celeron J3355 2x2GHz -TDP 10W -CPU Mark 1333 -Single Thread 884
3200/10,9 = 293 Mbps OpenVPN performance (estimate) -

Just finished putting my box together.
- J3355B-ITX
- 2 x (2GB) DDR3L 1600
- 5400 rpm drive
- Dual port Intel Pro /1000
- Antec ISK300-150 Case
All default settings…
Best I got I was 100Mbps down 232Mbps up.
I'll start playing with settings soon...
-
Hmm, I would not have expected such a big difference there.
Are you seeing any errors on the WAN interface itself?
Do you have fast-io set or send/rec buffers increased? There are knobs for that in the gui in 2.4, you have to add them as custom settings in 2.3.

hmmm, somethings definitely wrong here, others have reported faster speeds on that cpu without even maxing out yet.

That was with default settings right after installing pfSense.
Still haven't got a chance read on wiki for tweaks, but added:
fast-io
sndbuf 524288
rcvbuf 524288under VPN custom options, I was able to get 198Mbps down 234Mbps up. CPU was around 60%.
-
No errors on WAN I assume then?
That's a significant improvement! Still a bigger difference between down and up then I'd expect though.

The reason for this is that the Flash based speedtest.net tool does not account for LZO compression, which is built into the OpenVPN protocol.
did you try beta.speedtest.net I believe that doesn't use flash.
I have i3-7350K and I tried disabling compression and it didn't seem to make a difference, I am able to hit around 700mbs to 800mbs. Maybe i'm not disabling it correctly.
Hmm, you might be correct. I just tried the beta version and still reached 765 Mbps regardless of compression. Maybe its not the compression after all.
I think it's safe to say you can reach around 750 Mbps with OpenVPN on PIA with a G4400 processor (a $50 chip!). It might be the sweet spot for anyone with a 1000 mbit connection, unless you're trying to reach 900 or something but I'm not quite sure the CPU is the bottleneck for that.
-
The fact it's flash based should make no difference there. The only thing that matters is what their test data is, if it's compressible.
That's an impressive result if you're seeing that without compression. Both in terms of the CPU's ability and PIAs.

Well, the incorrect accounting for LZO is often connected to some speedtests using Flash. For example here: "it is very important to note that using flash-based speed tests like speedtest.net are unrealible for VPN services. This is because VPN services use compression to increase the speed that data flows across the network. Some flash based speed test servers do not properly account for this" (https://vikingvpn.com/speed). More in general it might not be Flash that's the issue, but for speedtest.net its a problem apparently.
But quite happy indeed, especially as I'm using some refurbished Lenovo M700 SFF with a Chinese Ebay Intel I350-T4. Great job for pfsense as well, its unfortunate they switched off the donations.

Yeah I know, but those are not really that useful for me. I'll just buy some stickers or something ;)
OpenVPN speed has been steady between 700-800 Mbps.

Which wiki is that? Looking to optimize my j3355 as well.

Do you mind sharing your hardware build/partlist?
I'm looking into purchasing something similar and i like your idle power usage of 13watts.Thanks.

Don't know about any wiki, but optimize OpenVPN with fast-io and buffers. Read here:

Sure, I'm using a prebuild Lenovo M700 SFF that I got really cheap with a platinum rated PSU (to quote Lenovo's website: "ENERGY STAR 6.1, ULE Gold, EPEAT Gold, and 85% efficiency with 80+ Platinum power supply unit", I'm not sure that's saying all that much though). Specs are: Intel G4400 dual core, 4 GB DDR4 memory, it came with a HDD but switched it for a cheap Kingston SSD and I added an Ebay Chinese I350 T4 NIC. I unplugged the CD drive and USB connectors and some other stuff not used. Speedstep is enabled and the CPU is often running around 1.5-2.0 Ghz when idle. Now I've monitored it over a longer time, the average idle power consumption usage has been around 15 watts. The case is really cool as well, usually around 25 degrees.
When building yourself, it's probably best to get a Pico PSU and search for a power efficient motherboard.

You could trying out to enable PowerD (high adaptive) of not done yet, to get perhaps less then 15 watts back.
or did you enable the PowerD (high adaptive) option? -
