The performance concern of AES (RijndaelManaged) in .NET
I intend to encrypt large data (around 3-5 MB) with **RijndaelManaged**. Is there any performance issue\suggestion on doing so? 

Thanks

            RijndaelManaged rijndaelCipher = new RijndaelManaged();
            rijndaelCipher.Mode = CipherMode.CBC;
            rijndaelCipher.Padding = PaddingMode.PKCS7;
            rijndaelCipher.KeySize = 128;
            rijndaelCipher.BlockSize = 128;
