Updraded to Quad Core Atom E3845 PIA VPN Now Very Slow 2.4.1

sheen73

Hi All,

I have been running Pfsense in Hyper -V on both 2.3.4 and 2.4.1 with 2 cores of an E3 1226 V3 XEON and I am able to basically max my internet speed using PIA @ 200Mbps. I got tired of losing internet when having to work on my server with Hyper-V so I purchased a Protectlii.

Long story short, max I can get now is 70ish Mbps. I tried 2.3.4 and 2.4.1. CPU usage from Tops seems ok so I don't know what gives. I even get max performance on an old AMD 9550 quad core phenom.

Tops CPU usage
2.3.4 20%
2.4.1 60%

Any thoughts on what to check? I am running 2.4.1 on my AMD box and running tests on the protectli using a VM at same time.

I installed Pfsense 2.4.1 on my spare system i5 7500T and rebuilt PIA VPN from scratch and I have the same problem. So I would guess the PIA VPN setting that needs to be different?

Original settings = 200Mbps internet speed

I have changed these settings

On 2.4.1 with i5 processor = 20Mbps

explicit-exit-notify 2
ifconfig-nowarn
tls-client
persist-key
persist-tun
persist-remote-ip
remote-cert-tls server
keepalive 10 120
reneg-sec 0
auth-nocache
fast-io
sndbuf 524288
rcvbuf 524288

Or

persist-key
persist-tun
persist-remote-ip
remote-cert-tls server
keepalive 10 120
reneg-sec 0
auth-nocache
fast-io
sndbuf 524288
rcvbuf 524288

or PIA suggested settings

persist-key
persist-tun
remote-cert-tls server
reneg-sec 0

Compression is adaptive LZO legacy. looks closest to 2.3.4 adaptive compression. So what gives here?

I’m using the latest pfsense on a sg2220 with strong encryption.. my udp Connection is my FULL internet speed.. you might email PIA for the directions

I also have aes ni enabled

Well i seem to be back to normal. I had the test pfsense behind a VM and that seemed to be affecting it. Connected my i5 Pfsense to my main network and performance is ok. It's a bit erratic if I change anything, going from 200 Mbps to 40 then back. Could be PIA.

I have the same issue and the same device from amazon that sheen73 has, I have a Gigabit connection, with PIA defaults I only get 40Mbps :(
In the UI I changed the Send/Receive Buffer to 512K and UDP Fast I/O to true.

My speed increased to 130Mbps… all my NICs support Gigabit.
