I’m two days now into testing a physically isolated 220.127.116.11 GW and I’m having big problems with network stability + speed. That is to say, I encounter a very bad network performance with both the GW and the connected workstation host. At times it works with acceptable Tor network performance (then it randomly stalls) but more often than not I have 1-2 KBit/s DL speed, going down to 500 Bit/s, so basically not usable.
I did thorough testing to isolate the issue:
- Booting the GW hardware from a Linux Live CD and downloading from the very same Debian mirror the GW is using as a repository -> fast (through clearnet). GW hardware is OK.
- I’m using Tails on a daily basis with the very same upstream connection -> fast (through Tor - via Tails).
- I tested the network performance between the GW and the workstation host utilizing iperf -> fast at 90-95 MBit/s.
- I switched Tor curcuits on the GW several times to make sure it’s not a particular Tor curcuit that’s failing.
I come to the conclusion that the GW implementation itself (and/or Debian) needs to be the issue here. Maybe the Whonix firewall (it feels like a clogged tube)? That is to say, even “apt-get update” takes forever to complete. I noticed that if it works for a minute or so, it just randomly stalls and is back to 1-2 KBit/s, going down to 500 Bit/s.
Now, I’m asking for support here. How may I troubleshoot this further? I read that at least one other community member has similar issues with network performance (with Whonix 7)*. I encounter the very same thing with the 18.104.22.168 GW here.
