Now I have more numbers :) read from a device through dm-crypt with aes-cts-plain, 256-bit mode (512bit keysize for cryptsetup) without this patch: 54MB/s with plain dd(blocksize 512b), 51MB/s with dd and a blocksize of 512kib (Yes, it's slower with a larger blocksize!) with this patch: 63MB/s with dd and a blocksize of 512b, 64MB/s with a blocksize of 512k (This time the larger blocksize was a little bit faster in each test) I did 5 tests for each combination, top shows everytime ~90% user and ~0% wait Stefan -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
