I'm getting annoying Latency values with qos statistics workload latency show. The only value that is bad is the Network Latency, 4ms+ over Fibre Channel. I tried researching what the Network-Part of the output is, but didn't succeed - I only found out that its the Network Subsystem, but don't understand what exactly is meant by this maybe someone had a issue like this. Does anyone have a clue what the Network Subsystem is?
#AFF Latency - Network subsystem

i've always understood it to be the internal protocal mechanism.
there's this kb -https://kb.netapp.com/on-prem/ontap/Perf/Perf-KBs/Slow_lun_access_with_high_latency_from_Network_subsystem. not sure if it's applicabe here.
