| 48 | # (i) compared to older gcc 3.x one can observe >2x improvement on | |
| 49 | # most platforms; | |
| d5487a45 AP |
50 | # (ii) 2xSSSE3 is code path optimized specifically for 128 bytes used |
| 51 | # by chacha20_poly1305_tls_cipher, results are EVP-free; | |
| a98c648e AP |
52 | # (iii) this is not optimal result for Atom because of MSROM |
| 53 | # limitations, SSE2 can do better, but gain is considered too | |
| 54 | # low to justify the [maintenance] effort; | |
| d5487a45 AP |
55 | # (iv) Bulldozer actually executes 4xXOP code path that delivers 2.20 |
| 56 | # and 4.85 for 128-byte inputs; | |
| cded9513 AP |
57 | # (v) 8xAVX2, 8xAVX512VL or 16xAVX512F, whichever best applicable; |
| 58 | # (vi) even though Skylake-X can execute AVX512F code and deliver 0.57 | |
| 59 | # cpb in single thread, the corresponding capability is suppressed; | |
