correct endianness

You should be able to get some advantage by ignoring the endian correcting. Won't be enough though.

I don't really have an opinion on what to use though. I've been through the process of trying to find something that fits in a particular performance bound and I've always found that the key to finding it is to look very deeply at the security requirements, usually there is something to be gained by figuring out exactly what meets your security requirements. I'd also take a close look at the usability requirements, there may actually be some gains to be made through desychronising things, the user expects something to happen immediately, but what does the user actually expect?
