I have been testing the performance of AES, RC4, IDEA, CAST, DES in Crypto++ 5.1 package. The speed up of RELEASE build is about 4 times. Can somebody explain the reason to me a little bit. I have tried to use the same compile flags in other computation complex program, but didn't see the same improvement. I would very much love to learn these speedup tactics and apply to my own program. Any advice or related resources are welcome. Thanks.
