POHMELFS crypto processing performance.

If you expected a miracle, it did not happen, so I just present a picture, where I compared plain async in-kernel NFS server (no encryption, no checksumming) versus POHMELFS, which performed SHA1 hashing and AES-128-CBC encryption of the whole data channel.
Block size used in iozone test is 8KB, filesize - 8GB, 1GB of RAM.
