Performance Issues with >40 pages

[caseybeck10]

Hi team,

I'm having trouble with the editors performance when pages reach 40 and above. The editor lags when typing multiple characters in a short space of time.

Is this a known problem, and if so, what can be done to mitigate the performance issues?

Thank you!

大家好，

当页面数量达到40页及以上时，我遇到了编辑器性能方面的问题。在短时间内输入多个字符时，编辑器会出现卡顿。

这是一个已知的问题吗？如果是的话，有什么办法可以缓解性能问题？

谢谢！
