I’ve been testing Longhorn for a while and the power and easy use of this storage backend is amazing.
What surprised me from beginning was sluggish performance, 10x slower than pod with mounted directory directly on the same host, some numbers below:
Mounted same folder to pod
Rancher master and node are VMs running on top of Hyper-v with Storage pools where are 4 SSD drives binded in one big pool.
As I haven’t seen discussed anywhere, I assume it’s something with my setup. How performs your Longhorns in the wild?
