若是PyPy快6.3倍，爲何我不該該使用PyPy而不是CPython？

問題：

I've been hearing a lot about the PyPy project. 我一直聽到不少關於PyPy項目的消息。 They claim it is 6.3 times faster than the CPython interpreter on their site . 他們聲稱它比他們網站上的CPython解釋器快6.3倍。

Whenever we talk about dynamic languages like Python, speed is one of the top issues. 每當咱們談論像Python這樣的動態語言時，速度是最重要的問題之一。 To solve this, they say PyPy is 6.3 times faster. 爲了解決這個問題，他們說PyPy的速度要快6.3倍。

The second issue is parallelism, the infamous Global Interpreter Lock (GIL). 第二個問題是並行性，臭名昭着的全球口譯鎖 （GIL）。 For this, PyPy says it can give GIL-less Python . 爲此，PyPy表示它能夠提供無GIL的Python 。

If PyPy can solve these great challenges, what are its weaknesses that are preventing wider adoption? 若是PyPy能夠解決這些巨大的挑戰，它的弱點是什麼阻礙了更普遍的採用？ That is to say, what's preventing someone like me, a typical Python developer, from switching to PyPy right now ? 也就是說，什麼阻止像我這樣的人，一個典型的Python開發人員， 如今切換到PyPy？
