Are you happy with the latency?
The wired buffer bloat screenshot seems quite high to me at 53 ms. Not sure if it's router or something else related. Have you tried connecting directly through the modem?
In my setup, FTTH of the GPON variety (1000/400), I get around 5 ms latency on the buffer bloat page. My old FTTC setup (1000/60, fiber to the curve + COAX through the building) was around 8.
My setup is GPON box -> managed switch -> Router (virtualized on KVM with pass-through NICs) -> managed switch (again) -> 2nd managed switch -> PC.
- giuliomagnifico 4y agoI’m very happy with the bufferbloat (0ms) not quite with the latency but I can’t do much, is my ISP that has about 15/20ms ping time. The fiber arrives only to the street cabinet, and then there’s a copper cable to my home, I don’t know how you can have 1000/60 on FTTC setup, this is absolutely impossible in my country (Italy), we can have 200/20 max speed on FTTC (and this is what I’m using). There’re already the fiber cables on the street, I’m waiting for the vertical lines to my home.
- vladvasiliu 4y ago> I don’t know how you can have 1000/60 on FTTC setup This was in an apartment building in Paris, not a detached house. It was a quite common setup when fiber started rolling out: it would arrive in the basement and apartments would be connected through the existing coax (TV) cables. Checking Wikipedia, maybe FTTB is a more appropriate term. Now it's mostly GPON FTTH. --- edit: regarding the latency, your setup adds around 30 ms of latency, which to me seems rather high.
- giuliomagnifico 4y agoOh okay, then FTTB is more appropriate. Anyway the 30ms it’s only on this service/server, my setup adds about 1-1,5ms: https://www.speedtest.net/result/i/5236800213 https://www.speedtest.net/result/i/5236800213 Ping time from router to AP root@R4S:~# ping 192.168.1.3 PING 192.168.1.3 (192.168.1.3): 56 data bytes 64 bytes from 192.168.1.3: seq=0 ttl=64 time=1.150 ms64 bytes from 192.168.1.3: seq=1 ttl=64 time=1.252 ms64 bytes from 192.168.1.3: seq=2 ttl=64 time=1.117 ms64 bytes from 192.168.1.3: seq=3 ttl=64 time=1.170 ms64 bytes from 192.168.1.3: seq=4 ttl=64 time=1.210 ms64 bytes from 192.168.1.3: seq=5 ttl=64 time=1.204 ms64 bytes from 192.168.1.3: seq=6 ttl=64 time=1.232 ms64 bytes from 192.168.1.3: seq=7 ttl=64 time=1.190 ms64 bytes from 192.168.1.3: seq=8 ttl=64 time=1.207 ms^C --- 192.168.1.3 ping statistics --- 9 packets transmitted, 9 packets received, 0% packet loss round-trip min/avg/max = 1.117/1.192/1.252 ms

- giuliomagnifico 4y agoThanks, I inserted two spaces before the text but it didn’t format all the code, just the first line, maybe because I’m on mobile?
