Not sure what you mean by "prestanda" here. 

Linux NFS is just fine, but comes configured in a way that typically
takes a 4x speed hit. The default NFS read/write size in Linux is 1024
for historical reasons. For better performance on disks mounted from
Solaris or IRIX NFS servers, set wsize=4096,rsize=4096 in the options
in /etc/fstab for NFS mounted disks.
