Eclipse is always slow when coding

The amount of code edited by eclipse is around 20,000.

The following two situations will occur and the response will be half a beat

I. Grammar checking is not enabled, line breaks are enabled

II. When grammar check is turned on

My computer configuration:

This is when eclipse edits code. For example, I add a piece of code in it:

$str = 'nimeide';

This is how he reacted:

$str = '

Delay about 0.5 - 1.2s

$str = '';

How to solve this delay problem? ?
