Keeping /data directory on dNFS share makes it extremely slow ad notusable

Hi,

 

I have migrated all my data from LVM partition to dNFS mount points and see that the performance is severely impacted. Are there any recommendations or best practices that needs to be incorporated to achieve desired performance. Ours is a reliable storage from NetApp and oracle utilizes the storage without any issues.

Thanks & Regards,

Can you use "jumbo" IP frames so that an 8KB block fits into one frame?
