Hello,
I have replaced my old DSL connection (2Mbps) by a professionnal
FTTH/4G one.
CISCO FTTH adapter

netbsd----Linux

lan
NetBSD and Linux (devuan) servers are directly connected to Cisco
adapter with public IPv4 addresses. No traffic shapers, only QoS
(iptables TOS on Linux side, altqd on NetBSD side).
On Linux, I got :
- 950 Mbps downlink;
- 295 Mbps uplink.
ISP announces 1 Gbps down and 300 Mbps up.
On NetBSD (-10) or workstations on LAN:
- 400 Mbps downlink;
- 4 (!) Mbps uplink, yes, 4 Mbps.
Of course, these results were done in the same configuration (firefox on
Linux and NetBSD console and this test: https://www.nperf.com/fr/). On
NetBSD, I have tried with and without altqd.
Network configuration on NetBSD server is complex:
- wm0, wm1: bridge0 connected to two NAS (iSCSI)
- wm2: WAN access
- wm2, wm4: lagg0 connected to LAN (through a Cisco switch)
- re0: connection to Linux box (DMZ)
Kernel shows:

I suppose I have to tune some parameters to obtain a better throughput,
mainly on uplink.
Help will be welcome.
Best regards,
JKB
