Hello all,
I run small ISP. All routers and firewalls run OpenBSD.
Reticently, client started to complain that their Citrix based systems
started to drop connections.
After some research, they tested with iperf and clearly see droped UDP
packets between my routers.
After that, I made test lab, and the results are not very nice.
I tested with iperf between directly connected (via Juniper EX4200
switch) OpenBSD 6.7 amd64 MP, dmeseg of sender and server are below.
APU Sender--->Juniper EX4200 ---> Supermicro Server
iperf -c serverIP -u -t 60 -b 10M -p 5003 no drops
iperf -c serverIP -u -t 60 -b 20M -p 5003 average 2% drops
iperf -c serverIP -u -t 60 -b 30M -p 5003 avarage 15% drops
iperf -c serverIP -u -t 60 -b 40M -p 5003 avarage 20% drops
iperf -c serverIP -u -t 60 -b 50M -p 5003 between 25% drops
Also tested other lab with simmular results
APU Sender--->Juniper EX4200 ---> Supermicro Forwardig ----> TPlink
switch ----> Supermicro Server
Is this expected or know behavior?
Am I missing some tweaks?
Is the hardware not powerful enough?
Any ideas and suggestions are appreciated.
Thanks for your help,
Ivo
