Optimizing NFS

Recommended Posts

As above..


I've found the following as a client option gives me the best performance :


-o noacl,nocto,rsize=32768,wsize=32768


Alongside an async export.


I can get 100 megabytes per second sequential throughtput from an ubuntu client vm to an unraid 5 server vm using those options in conjunction with other sensible vmware optimisations (correct virtual nic, vmtools installed etc).


I'm not sure how random i/o would fare though. And some of those options might not be desirable depending on your usage..
