[Question]关于Pyarmor 脚本的性能问题

[sunbo394]

新版本python下加密函数效率降低，有办法处理吗？

python3.8.6： 0.35s
python3.10.9： 3.59s
python3.11.0： 5.8.2s

下面是配置选项，三个版本的选项都是一样的：

请修改原来的报告，删除不必要的日志，使用良好的格式提交如下内容：

1. 没有加密前的性能
2. 加密后的性能
3. 如果可能最好提供一个测试脚本（不要使用第三方库就可以运行）
4. 加密使用的完整命令行参数，只需要拷贝前四行的输出，不需要后面的日志
5. 所有使用过的完整的 cfg 命令以及选项，不需要拷贝命令的输出

[jondy]

下面是示例，请参考这样的模式报告

加密命令和环境

$ pyarmor cfg wrap_mode 1
$ pyarmor gen --assert-call foo.py

INFO     Python 3.9.0
INFO     Pyarmor 8.1.6 (pro), 005068, boot armor
INFO     Platform darwin.x86_64

加密前性能

• Python 3.9.0, 1.2s
• Python 3.10.1, 1.0s

加密后性能

• Python 3.9.0, 1.4s
• Python 3.10.1, 1.2s

示例脚本

    import sys

    def sum2(a, b):
        return a + b

    def main(msg):
        a = 2
        b = 6
        c = sum2(a, b)
        print('%s + %s = %d' % (a, b, c))

    if __name__ == '__main__':
        main('pass: %s' % data)

m.py

class X:

def func():
    ret = []
    for i in range(1000000):
        ret.append(X())
    return len(ret)

@jondy 3.11.0 环境已经补充提交， 3.8.6 环境下提示错误

3.10.9 环境下提示下执行结果 (操作系统window11, 通过 scoop 安装的不同python版本)

$ python3 test.py
origin: 0.9s
pyarmor: 1.5s

[jondy]

INFO Python 3.11.0
INFO Pyarmor 8.1.6 (basic), 001767, non-profits
INFO Platform windows.x86_64
输出： 加密前0.8，加密后2.5
origin: 0.8s
pyarmor: 2.5s

循环了 100万次，多了 1.7 秒，这个性能基本是在期望之中的。

如果对性能要求很高，请关注最新的文档更新，关于各种选项对性能影响的文档（英文版）在这周就会完成，可以参考该文档选择合适的选项。

可以先测试一下选项 --no-wrap 看看能否提高性能。

[jondy]

另外还有性能测试需要注意的一点，不管是运行原来的脚本，还是加密后的脚本，需要把所有 __pycache__ 的目录都删除了，如果存在 __pycache__，那就意味着执行时间里面没有包含编译脚本的时间。

但是编译脚本（.py->.pyc)是很花费时间的，尤其是大脚本。
