Slow Network Performance

[djdwosk97]

I've been using Plex without any problems remotely for a few years, but for the last couple of months I have experienced horrible upload speeds (from Plex -- in the form of buffering every few seconds) and I'm not sure why -- at least I suspect that's the problem. The utilization of everything on the server looks low, and nothing has changed, I also have 35mbps upload speeds (I can't easily test it atm as I don't have direct access to the network that the server is on, but I can run a speedtest through my extremely slow/shitty VPN and through that network and get 3-10 Mbps upload, so without the VPN in the way, I have no doubts it would be 20-30 Mbps).

Any ideas what could be causing the problem (/is there a dummy service I can upload to from command line if I SSH into the server)?

Specs in sig.

Did you find the culprit? If not, what is the Used % on the pool?

It's 80-90% -- I don't recall off the top of my head and I can't check at the moment, but nothing changed between when it was performing fine and when the remote upload speeds started to be limited.

Having the pool that full does start to impact performance. The other possible culprit: are you using jumbo frames, and if so, with which driver?

Local streaming isn't a problem though (I've tested up to 30 Mbps~ or so and it was fine) -- just remote streaming (which struggles around 1-2 Mbps).

Where would I check that?

Any ideas?

(I tried with jumbo frames enabled and disabled in the router settings -- there was no difference).

How does a normal internet speed test? As fort eh VPN, depending on how its configured, you may need to set MSS clamping or a smaller MTU on the VPN interface as you cant encapsulate 1500 bytes and still have 1500 bytes ;)

Consistently between 25-30 Mbps upload without the VPN in the way.

Hello all

I am by no means a network capable guy. I am very new to freenas and still learning how to use it. I am running 11.2 RC1. When i login the dashboard present itself, the band with shown is in downloads 0.0011 mbps and .0003MBps in uploads. I never seen it go much higher. My setup is pretty vanilla and I am in the process of learning to install Emby (which now almost works) I have my NAS directly connected to my router. wwwwhat have not done? Thank you in advance for your assistance
