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 ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
