it's known to all that ,sometimes higher version is far more slow than low version

this is a example.

```mathematica
Clear["Global`*"]; Plot[Sin[x], {x, 0, 5}] // AbsoluteTiming
```

on my computer

So is there a way to use low version in high version?

The reason why I don't use low version directly is that high version has more functions,which is more convenient.

**thx to the link in the comment.I find this.**
