NFS is slow for non-cached NetApp reads
 
I'm having some issues with my NetApp. NetApp is not telling me, but kinda say that 50MB/sec for non-cached data from an x3850m2 is "good" and that we need to thread things up. Well, I feel 50 is a little slow. The int environment runs 3650, and non-cached is 80MB/sec there.

What kinda of tuning or threading needs to take place to bring these non-cached reads up to par? cached reads are 350 and 500 for both nodes.. So I know we can pull data from them, some how adding in the latency for the disk read is chocking everything down.
