Mount of AIX jfs2 filesystem on Linux server extremely slow

I am trying to mount an AIX jfs2 filesystem as an nfs mount onto a
linux server. The fs does mount but takes close to 2 minutes to mount.
Am using the following on the /etc/exports file:
$cat /etc/exports
/govind -ro,root=cairvcnwad002,access=cairvcnwad002

On the Linx server I am doing the following:
[root@cairvcnwad002 /]# mount -v apollo:/govind /mnt/delta/
mount: no type was given - I'll assume nfs because of the colon
mount: trying 172.31.1.17 prog 100003 vers 3 prot tcp port 2049
mount: trying 172.31.1.17 prog 100005 vers 3 prot udp port 32807
apollo:/govind on /mnt/delta type nfs (rw,addr=172.31.1.17)

I have tried using the -tnfs option too, still the same response. Also
tried without -v, with -n, -o tcp,bg,hard...still no luck.

Help please.
