If it's 100% read-only, you could probably use it safely. Make sure its filesystem on the NFS server is mounted read-only, and obviously all the clients' NFS mounts must also be read-only. As for "largely read only" - if there are any writers at all, all bets are off. LMDB automatically detects read-only filesystems, and turns off its locking in that case, so it should perform as well as anyone could expect NFS to perform.
