All above results are consistently better. This 41 # module also provides better performance for block sizes smaller than 42 # 128 bytes in points *not* represented in the above table. 43 # 44 # Looking at the results for 8-KB buffer. 45 # 46 # CFB and OFB results are far from the limit, because implementation 47 # uses "generic" CRYPTO_[c|o]fb128_encrypt interfaces relying on 48 # single-block aesni_encrypt, which is not the most optimal way to go. 49 # CBC encrypt result is unexpectedly high and there is no documented 50 # explanation for it. Seemingly there is a small penalty for feeding 51 # the result back to AES unit the way it's done in CBC mode. There is 52 # nothing one can do and the result appears optimal. CCM result is 53 # identical to CBC, because CBC-MAC is essentially CBC encrypt without 54 # saving output. CCM CTR "stays invisible," because it's neatly 55 # interleaved wih CBC-MAC. This provides ~30% improvement over 56 # "straghtforward" CCM implementation with CTR and CBC-MAC performed 57 # disjointly. Parallelizable modes practically achieve the theoretical 58 # limit. 59 # 60 # Looking at how results vary with buffer size. 61 # 62 # Curves are practically saturated at 1-KB buffer size. In most cases 63 # "256-byte" performance is >95%, and "64-byte" is ~90% of "8-KB" one. 64 # CTR curve doesn't follow this pattern and is "slowest" changing one 65 # with "256-byte" result being 87% of "8-KB." This is because overhead 66 # in CTR mode is most computationally intensive. Small-block CCM 67 # decrypt is slower than encrypt, because first CTR and last CBC-MAC 68 # iterations can't be interleaved. 69 # 70 # Results for 192- and 256-bit keys. 71 # 72 # EVP-free results were observed to scale perfectly with number of 73 # rounds for larger block sizes, i.e. 192-bit result being 10/12 times 74 # lower and 256-bit one - 10/14. Well, in CBC encrypt case differences 75 # are a tad smaller, because the above mentioned penalty biases all 76 # results by same constant value. In similar way function call 77 # overhead affects small-block performance, as well as OFB and CFB 78 # results. Differences are not large, most common coefficients are 79 # 10/11.7 and 10/13.4 (as opposite to 10/12.0 and 10/14.0), but one 80 # observe even 10/11.2 and 10/12.4 (CTR, OFB, CFB)... 81 82 # January 2011 83 # 84 # While Westmere processor features 6 cycles latency for aes[enc|dec] 85 # instructions, which can be scheduled every second cycle, Sandy 86 # Bridge spends 8 cycles per instruction, but it can schedule them 87 # every cycle. This means that code targeting Westmere would perform 88 # suboptimally on Sandy Bridge. Therefore this update. 89 # 90 # In addition, non-parallelizable CBC encrypt (as well as CCM) is 91 # optimized. Relative improvement might appear modest, 8% on Westmere, 92 # but in absolute terms it's 3.77 cycles per byte encrypted with 93 # 128-bit key on Westmere, and 5.07 - on Sandy Bridge. These numbers 94 # should be compared to asymptotic limits of 3.75 for Westmere and 95 # 5.00 for Sandy Bridge. Actually, the fact that they get this close 96 # to asymptotic limits is quite amazing. Indeed, the limit is 97 # calculated as latency times number of rounds, 10 for 128-bit key, 98 # and divided by 16, the number of bytes in block, or in other words 99 # it accounts *solely* for aesenc instructions. But there are extra 100 # instructions, and numbers so close to the asymptotic limits mean 101 # that it's as if it takes as little as *one* additional cycle to 102 # execute all of them. How is it possible? It is possible thanks to 103 # out-of-order execution logic, which manages to overlap post- 104 # processing of previous block, things like saving the output, with 105 # actual encryption of current block, as well as pre-processing of 106 # current block, things like fetching input and xor-ing it with 107 # 0-round element of the key schedule, with actual encryption of 108 # previous block. Keep this in mind... 109 # 110 # For parallelizable modes, such as ECB, CBC decrypt, CTR, higher 111 # performance is achieved by interleaving instructions working on 112 # independent blocks. In which case asymptotic limit for such modes 113 # can be obtained by dividing above mentioned numbers by AES 114 # instructions' interleave factor. Westmere can execute at most 3 115 # instructions at a time, meaning that optimal interleave factor is 3, 116 # and that's where the "magic" number of 1.25 come from. "Optimal 117 # interleave factor" means that increase of interleave factor does 118 # not improve performance. The formula has proven to reflect reality 119 # pretty well on Westmere... Sandy Bridge on the other hand can 120 # execute up to 8 AES instructions at a time, so how does varying 121 # interleave factor affect the performance? Here is table for ECB 122 # (numbers are cycles per byte processed with 128-bit key): 123 # 124 # instruction interleave factor 3x 6x 8x 125 # theoretical asymptotic limit 1.67 0.83 0.625 126 # measured performance for 8KB block 1.05 0.86 0.84 127 # 128 # "as if" interleave factor 4.7x 5.8x 6.0x 129 # 130 # Further data for other parallelizable modes: 131 # 132 # CBC decrypt 1.16 0.93 0.93 133 # CTR 1.14 0.91 n/a 134 # 135 # Well, given 3x column it's probably inappropriate to call the limit 136 # asymptotic, if it can be surpassed, isn't it? What happens there? 137 # Rewind to CBC paragraph for the answer. Yes, out-of-order execution 138 # magic is responsible for this. Processor overlaps not only the 139 # additional instructions with AES ones, but even AES instuctions 140 # processing adjacent triplets of independent blocks. In the 6x case 141 # additional instructions still claim disproportionally small amount 142 # of additional cycles, but in 8x case number of instructions must be 143 # a tad too high for out-of-order logic to cope with, and AES unit 144 # remains underutilized... As you can see 8x interleave is hardly 145 # justifiable, so there no need to feel bad that 32-bit aesni-x86.pl 146 # utilizies 6x interleave because of limited register bank capacity. 147 # 148 # Higher interleave factors do have negative impact on Westmere 149 # performance. While for ECB mode it's negligible ~1.5%, other 150 # parallelizables perform ~5% worse, which is outweighed by ~25% 151 # improvement on Sandy Bridge. To balance regression on Westmere 152 # CTR mode was implemented with 6x aesenc interleave factor. 153 154 # April 2011 155 # 156 # Add aesni_xts_[en|de]crypt. Westmere spends 1.33 cycles processing 157 # one byte out of 8KB with 128-bit key, Sandy Bridge - 0.97.
