Slow down vscode UI typing response.

[HuazyYang]

When user is typing with spell-checker enabled, UI response is much slow relative to extension disabled, any way to tune spell checking frequency when user is typing or just use lazy checking when file modifcation changed?

@HuazyYang,

It is possible to control the delay using: cSpell.spellCheckDelayMs. Changing it to 500 or 1000 might make things better.

The spell checker should not have a noticeable impact on the UI. If possible please share your configuration. Please consider restarting VS Code to see if it still happens.

Please provide the following information:

• What is the file type of the documents that are slowing the editing down?
• Did you add any RegExp patterns, cSpell.ignoreRegExpList or cSpell.includeRegExpList settings?
• How big are the files you are editing?

There are a few cases where it can happen:

1. If spell issues do not show up, it is possible that the extension didn't install correctly -- this generally gives an error, but it can also just be slow.
2. Expensive regular expressions.

@HuazyYang,

I would like to find out the cause. Do you have any more information?
