See [1] subdir speed-test/ If you want to play with it, all you need to do is to add your init/encryption/fini code into cryptoperf-skcipher.c. The key is that cp_ablkcipher_enc_test/cp_ablkcipher_dec_test performs only the encryption/decryption operation (setkey, etc is done in the init call). The speed measuring is done only over that function.
