Darren Tucker <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #6 from Darren Tucker <[email protected]> --- (In reply to tim from comment #4) > AES_CGM doesn't much slower than AES_CTR This varies a lot depending on the platform. For a counterexample (Ryzen 3900X), GCM is half the speed: $ openssl speed -evp aes-256-gcm Doing AES-256-GCM for 3s on 16 size blocks: 103804564 AES-256-GCM's in 2.99s Doing AES-256-GCM for 3s on 64 size blocks: 58949992 AES-256-GCM's in 2.99s Doing AES-256-GCM for 3s on 256 size blocks: 34661021 AES-256-GCM's in 3.00s Doing AES-256-GCM for 3s on 1024 size blocks: 11774310 AES-256-GCM's in 2.99s Doing AES-256-GCM for 3s on 8192 size blocks: 1690281 AES-256-GCM's in 2.99s Doing AES-256-GCM for 3s on 16384 size blocks: 853186 AES-256-GCM's in 3.00s $ openssl speed -evp aes-256-ctr Doing AES-256-CTR for 3s on 16 size blocks: 167022187 AES-256-CTR's in 2.99s Doing AES-256-CTR for 3s on 64 size blocks: 131872734 AES-256-CTR's in 3.00s Doing AES-256-CTR for 3s on 256 size blocks: 70440642 AES-256-CTR's in 2.99s Doing AES-256-CTR for 3s on 1024 size blocks: 23978238 AES-256-CTR's in 3.00s Doing AES-256-CTR for 3s on 8192 size blocks: 3358652 AES-256-CTR's in 2.99s Doing AES-256-CTR for 3s on 16384 size blocks: 1703078 AES-256-CTR's in 3.00s -- You are receiving this mail because: You are watching the assignee of the bug.
