Issue

High latency is observed on the cluster
FlexVols have .snapshot directory access enabled

Example: This packet trace with the nfs.name==".snapshot" filter shows quite a few hits (truncated for brevity) from Wireshark and tshark

username@windows-PC-wsl:/mnt/c/Users/username/Desktop$ tshark -Y "nfs.name==".snapshot"" -r "a2a-2432_20210609_040708(1).trc1" | head 109 0.000627 10.11.1.4 → 10.1.1.1 NFS 230 V3 LOOKUP Call, DH: 0xfc38f0fa/.snapshot 158 0.002363 10.1.5.47 → 10.1.1.1 NFS 230 V3 LOOKUP Call, DH: 0xfc38f0fa/.snapshot 202 0.015898 10.1.44.2 → 10.1.1.1 NFS 230 V3 LOOKUP Call, DH: 0xfc38f0fa/.snapshot 703 0.019168 10.8.1.22 → 10.1.1.1 NFS 230 V3 LOOKUP Call, DH: 0xfc38f0fa/.snapshot 725 0.019270 10.44.1.5 → 10.1.1.1 NFS 230 V3 LOOKUP Call, DH: 0xfc38f0fa/.snapshot 768 0.019566 10.1.5.32 → 10.1.1.1 NFS 230 V3 LOOKUP Call, DH: 0x9a03f34a/.snapshot 1198 0.044541 10.1.5.33 → 10.1.1.1 NFS 230 V3 LOOKUP Call, DH: 0xfc38f0fa/.snapshot 1484 0.047528 10.1.5.34 → 10.1.1.1 NFS 230 V3 LOOKUP Call, DH: 0x9a03f34a/.snapshot 1919 0.316793 10.1.5.35 → 10.1.1.1 NFS 230 [TCP ACKed unseen segment] [TCP Previous segment not captured] V3 LOOKUP Call, DH: 0xfc38f0fa/.snapshot 2078 0.318461 10.1.5.36 → 10.1.1.1 NFS 230 V3 LOOKUP Call, DH: 0xfc38f0fa/.snapshot
