I just looked at our main filer and realized we are using 8k NFS packets. With almost exclusively solaris 2.6 and 2.7 clients. I bet we would see a significant speed increase if we upped it, particularly with the large regressions being done on this Netapp. But, can I just log in and change the value? Will that affect existing mounts, and at what point would the new blocksize take effect? Or, can I only set it on reboot -- but even then the clients would have to remount the filesystem right? Someone help me out on the proper way to do this, and let me know if doing this causes harm in any way. Looking at nfsstat most of our operations are indeed nfs3.

b) There is no way to use w/rsize=32768 with NetApp with NFS3 over UDP. Why? I can do it when mounting from Solaris.
Did you set the nfs.udp.xfersize set to 32768? Like so....
