Would it have been that difficult to show how to run "openssl speed aes -multi 4" or whatnot so people could test on their own hardware?
Perhaps the recognition that even older hardware such as the quad core Opteron 2358 I tested on, delivers 350Mbytes/sec of AES256, would tend to undermine their argument.
350Mbytes/second of network throughput is roughly 3.5 Gbits/second (I usually multiple bytes * 10 to account for overhead); far beyond what most people would ever ask of a single server.
(this same hw does 900+ RSA 2048 bit signs/s, just for reference)
I don't disagree with your point, but this bit is faulty. If you want to account for some overhead you should multiply by a number lower than 8, not higher.
