No matter what you do, you will be limited by your network speed. Consider getting 10Gig network cards or Infiniband. All writes will need to hit both servers, so the max throughput you'll get is about 50MB/sec with a 1G card. You can get a full 100MB/sec by using the NFS/gluster connector to one of the servers (assuming your servers have 10G/Infiniband).
