Hi guys,
Thank you all for replys and sorry I was having enabled digest mode and I
did not get all messages in time.
Here are answers:
Message 2:
Client and server are virtual machines inside vmware environment which is
connected to 10gbps. Network is devided between virtual machines. Physical
servers are connected to Nexus switch with 10gbps.
Message 3:
We have try speeds with iperf, they are between 1 and 6 gbps, sometimes goes
to 8gbps - depends of the load of networks. All checks was done with sync mode
(NFS will be used for important data and we do not want to lose something).
Message 4:
Config is default, just installed and tested with NFSv3 NFSv4.
Message 5:
We did not enable jumbo frames on network.
For all: We are testing speed with this script (PHP7.4):

Hi guys,
we are setting NFS server on CentOS7 system. Everything working OK
except speed, speed over NFS very drop... if we run dd command directly
on server we are getting speed around 1,4Gbps, if we run from client
connected to NFS is 200Mbps.
Do you have maybe some advice what we need to check?
Thank you!
Best, Erik

Speed of network card in the server.
Speed of network card in the client.
Speed of any and all routers and switches between the server and the
client.

I would start with something like iperf to measure the actual network
throughput b/w the client and server. Once you have a baseline for that,
we'd have to know things like read and write buffer sizes, and sync
vs
async mode.

Make sure you have good speed of physical connection along the whole
path from server to client(s), enable Jumbo packets on all switches
along the path. NFS experts will add NFS specific tuning.
