M1 跑 openssl speed 测试， rosetta 竟然速度快好多

这算逆优化么 😂

结果：

arch -arm64e openssl speed -evp aes-256-gcm

LibreSSL 2.8.3

我的 M1Max 和你这个数据差不多

重新用 OpenSSL 跑了下，好像自带的 LibreSSL 有点问题

LibreSSL 没有 arm64 的汇编优化，只有 x86_64 的。OpenSSL 的指令集优化多一点。

另外可以用自带的试试 aes-128-gcm ，貌似有优化。

@linusyang 是的，好像 128 很快，原生比 rosetta 快了，差距并不大
