[Gluster-users] Solaris 10 client NFS performance very poor

Hello Avati,
Thanks for your quick response.  I had planned to upgrade to 3.3 at some 
point, mainly to take advantage of the NFS memory leak fix.

I am worried about upgrading after bad experiences with 3.1.0 and 
3.2.0.  Does anyone have any experience of upgrading from 3.2.6 to 3.3.0?
