I've spent a good amount of time benchmarking encryption operations, and I can say this: Even without AES-NI, CPU's in general are so darn fast, there's *still* no meaningful overhead to use AES-256. A single core, circa Pentium D or Core 2, could encrypt/decrypt a 1Gbit stream without AES-NI, using only about 30% to 35% of a single core. If you have AES-NI, it comes down to about 3% to 5% CPU utilization. And of course, nowadays you always have more cores, each of which are more powerful than those I benchmarked. _______________________________________________ Discuss mailing list [email protected] http://lists.blu.org/mailman/listinfo/discuss
