NFSv3 vs NFSv4 Storage on Proxmox: The Latency Clash That Reveals More Than You Think
(2025-07-04):When it comes to virtualization, many people still think that NFS isn’t suitable for serious workloads in their enterprise environment and that you need to rely on protocols like iSCSI or Fibre Channel to get proper performance. That mindset might have made sense years ago, but times have changed. Today, we have access to incredibly fast networks and not only in enterprise but even at home. It’s not uncommon to see 10 Gbit networking in home labs, and enterprises are already moving to 25, 40, 100, or even 400 Gbit infrastructure. So the bottleneck is no longer bandwidth rather than the protocol overhead and hardware interaction that really matters. NFS, despite being around for decades, is often underestimated. Many still think of it as a basic file-sharing protocol, not realizing how far it’s come and how capable it is when properly configured and used with the latest versions. Especially in ....
