16 | # Interface to OpenSSL as "almost" drop-in replacement for | ||
17 | # aes-x86_64.pl. "Almost" refers to the fact that AES_cbc_encrypt | ||
18 | # doesn't handle partial vectors (doesn't have to if called from | ||
19 | # EVP only). "Drop-in" implies that this module doesn't share key | ||
20 | # schedule structure with the original nor does it make assumption | ||
21 | # about its alignment... | ||
22 | # | ||
23 | # Performance summary. aes-x86_64.pl column lists large-block CBC | ||
24 | # encrypt/decrypt/with-hyper-threading-off(*) results in cycles per | ||
25 | # byte processed with 128-bit key, and vpaes-x86_64.pl column - | ||
26 | # [also large-block CBC] encrypt/decrypt. | ||
27 | # | ||

30 | # Core 2(**) 30.5/43.7/14.3 21.8/25.7(***) | ||
31 | # Nehalem 30.5/42.2/14.6 9.8/11.8 | ||
32 | # Atom 63.9/79.0/32.1 64.0/84.8(***) | ||
33 | # | ||
34 | # (*) "Hyper-threading" in the context refers rather to cache shared | ||
35 | # among multiple cores, than to specifically Intel HTT. As vast | ||
36 | # majority of contemporary cores share cache, slower code path | ||
37 | # is common place. In other words "with-hyper-threading-off" | ||
38 | # results are presented mostly for reference purposes. | ||
39 | # | ||
40 | # (**) "Core 2" refers to initial 65nm design, a.k.a. Conroe. | ||
41 | # | ||
42 | # (***) Less impressive improvement on Core 2 and Atom is due to slow | ||
43 | # pshufb, yet it's respectable +40%/78% improvement on Core 2 | ||
44 | # (as implied, over "hyper-threading-safe" code path). | ||
