I have worked a lot with NetApp filers and Oracle databases on Solaris.
With NFS and a 1gbit etherenet connection you should be able to reach around 50-90MB / sec in sequential reads/writes.
Check how your nfs/filer is working.. Create a large file on the nfs share with mkfile or dd command and check your throughput with iostat -xnpr while the file is beeing created.
also check your network card with netstat -i , do you have errors?
DirectIO is a good option but its not game breaking also change the rsize, wsize for nfs (64k) but thats just fine tuning.
but as the above poster stated, it would be great if you could post some numbers on how much IO the EMC did over FC
