We're planning to try replacing some Solaris web servers with FreeBSD machines in the near future. The documents are on a read-only NFS filestore connected to the web servers with CDDI. (Updates will stay on a Sun box.) Are we going to have nfs_realign problems if we use TCP in this situation or should we stick with UDP?
