Intense write latency on NFS...


Recommended Posts

I have built a 24 drive NFS target using UNRAID.

Dual XEON 5300 processors

32GB RAM

24 drives in BTRFS fronted by an SSD Cache.

10GB NICs all around

ESXi v7, attempting to clone from 15kRPM SAS RAID 0 volume to the NFS target

 

I get only 1.9Mbit/sec writing to the volume.

 

Attached is the behavior when cloning a VM to the NFS target from the local RAID0 ESXi host.

The write latency is crazy.

 

Anyone have thoughts?
