Hello All
i have a strange issue since that i updated my server from Freenas to Truenas 12 U1.1 , the ping latency on my local network is now very high (~10ms) but not only.
my server DL380 G10 is in prod since ~2years on Freenas without really pb (yes the smartpqi but it's a another story)
when i ping from a server the filer via the lan, i have a latency of ~10ms but if i use the arping it's ok
# ping 192.168.200.1
PING 192.168.200.1 (192.168.200.1) 56(84) bytes of data.
64 bytes from 192.168.200.1: icmp_seq=1 ttl=64 time=8.09 ms
64 bytes from 192.168.200.1: icmp_seq=2 ttl=64 time=14.1 ms
64 bytes from 192.168.200.1: icmp_seq=3 ttl=64 time=10.0 ms
by default the Lan is ok when i ping from the same server a another IP.
# ping 192.168.200.20
PING 192.168.200.20 (192.168.200.20) 56(84) bytes of data.

64 bytes from 192.168.200.20: icmp_seq=3 ttl=64 time=0.229 ms
i restart my filer , my switch , same issue on a another network with a different switch.
if i start a arping from the same server to my filer it's ok
# arping -I eno6 192.168.200.1
ARPING 192.168.200.1 from 192.168.200.10 eno6
