-speed: print cpu model
When somebody posts "gocryptfs -speed" results, they are most helpful together with the CPU model. Add the cpu model to the output. Example: $ ./gocryptfs -speed gocryptfs v2.2.0-beta1-5-g52b0444-dirty; go-fuse v2.1.1-0.20210825171523-3ab5d95a30ae; 2021-09-14 go1.17.1 linux/amd64 cpu: Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz; with AES acceleration AES-GCM-256-OpenSSL 862.79 MB/s AES-GCM-256-Go 997.71 MB/s (selected in auto mode) AES-SIV-512-Go 159.58 MB/s XChaCha20-Poly1305-OpenSSL 729.65 MB/s XChaCha20-Poly1305-Go 843.97 MB/s (selected in auto mode)
