Get a faster computer. If you are copying and pasting that amount of data then you may need to rethink what you are doing.

Solution 1

I noticed that setting WordWrap to false makes it much faster. However, you turn WordWrap on after the text box is filled with text, that operation becomes slow!

Probably, there are no other ways you can accelerate it.

[EDIT]
Another way is switching to WPF. It's generally faster; and the rendered text will appear sooner, due to a separate rendering thread.

If I set WordWrap to false ,How can I set textbox to have a Vertical scroll bar.I want to show all the characters in the text box.

This is not how WordWrap works. It's the horizontal scroll bar disappears. Also, all characters are always shown via scrolling, regardless of this option. It is ***absolutely*** irrelevant, but effect speed greatly. As I say in my next sentence, it's just wiping garbage under the carpet: you will have a problem when you set the option on again.

There is no a way to accelerate it, face it finally!
WPF can do faster, with a twist (separate rendering thread), but it is also generally faster.
