Hi, Thanks. Yes, I have tried to disable NFS 4 in storage and use vers=3 to mount the storage, but the performance difference is no more than 5%.

This is the same question, only append the url for the images. I have tested the storage performance of my storage system using three different methods: 1. Using the NFS protocol with a 10G network, on VMware ESXi, with a 4K block size and 100% sequential read operations.

Using the FC protocol with 16G , on Cloudstack, treating the LUN accessed via FC as a local disk, with a 4K block size and 100% sequential read operations.

The second is FC-SAN with Cloudstack (1.25), and the worst is NFS with Cloudstack. Even the NFS with ESXi is better than fc-san? I believe there may be some configurations that could improve the storage performance when using Cloudstack. I would greatly appreciate it if anyone could offer some advice or solutions to help me optimize the Cloudstack storage performance. Thank you very much for your attention. Best regards. Leo.
