Róża Luksemburg was a Polish Marxist, philosopher, economist, anti-war activist and revolutionary socialist.

Today we can seriously set about destroying capitalism once and for all. Nay, more; not merely are we today in a position to perform this task, nor merely is its performance a duty toward the proletariat, but our solution offers the only means of saving human society from destruction. -- Rosa Luxembourg

Rosa Parks was also an American activist in the civil rights movement best known for her pivotal role in the Montgomery bus boycott. The United States Congress has called her "the first lady of civil rights" and "the mother of the freedom movement".

People always said that I didn't give up my seat because I was tired, but that isn't true. I was not tired physically, or no more tired than I usually was at the end of a working day. I was not old, although some people have an image of me as being old then. I was forty-two. No, the only tired I was, was tired of giving in. -- Rosa Parks

It is also a TP-Link AC1750 v5 router that I use as a bridge. It was configured similarly to plastik, with a fresh OpenWRT (19.07.3) setup (see the OpenWRT hardware page), using the factory.bin image from the TP-Link stock firmware web interface.

Benchmarks

I performed some benchmarks at the request of people from #debian-quebec, provided below.

I unfortunately forgot to run the same benchmarks with the stock firmware, but that could have been difficult unless it ships with iperf3...

... which proves octavia is not the bottleneck: the tp-link is (and, unrelatedly, angela's gigabit adapter as well, but we could still reproduce without it).

So the 40Mbps is actually disappointing here. It's possible neighboring access points caused interference.

I had trouble connecting to the router over 5GHz and web browsing performance was bad (Wikipedia would not load properly). Still it said it was supposed to deliver 300mbps:

wlp2s0    IEEE 802.11  ESSID:"CrapN6-5GHz-emma"  
          Mode:Managed  Frequency:5.745 GHz  Access Point: B0:95:75:41:E7:C0   
          Bit Rate=300 Mb/s   Tx-Power=17 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=56/70  Signal level=-54 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:73   Missed beacon:0

So performance is also definitely disappointing here, although that could also be due to the hardware in angela, which wouldn't surprise me at this point.
