[CentOS] slow NFS speed

70-80MB/s is good for NFS/CIFS networking given the 4k block size and network latency.

It's not the MB/s driven by your storage system that get you it's the IOPS throttled by the network latency and two-way communication over it.

Subject: [CentOS] slow NFS speed

We upgraded from a 10/100Mbs to a 2 100/1000 bonding. We notice the
speeds of NFS to be around 70-80Mb/sec. Which is slow, especially with
bonding. I was wondering if we need to tune anything special with the
Network and NFS. Does anyone have any experience with this?

TIA
