Speed ​​up Eclipse when editing files with 2000+ lines

When I edit large files in eclipse (about 2000+ lines), editing the file becomes very slow. The text will appear a couple of seconds after entering it.

I tried it in an editor, for example, in notepad ++, and it handles the file perfectly.

I considered this issue to expedite the eclipse, but I had no luck with them. How can you speed up Eclipse?

Any thoughts on this are really appreciated, as I know that some of my friends are also having this problem.

The problem is the code folding function. If you really don't need to bend the code, turn it off.

Window-> Settings-> PHP-Editor-> Code Folding and unchecking the function Code folding.

Instead of trying to speed up Eclipse, it would be better to stylistically rip your 2000+ file into several small files. If this file is a Java class, for example, you probably have a God object, and you still need to split it.

Assuming this is a Java file, the reason it is slow while Notepad ++ is fast is because Notepad ++ just shows the file. Eclipse compiles, checks the compiler warnings, starts the error search / checkstyle / everything you installed, etc., some of which are time consuming and can take a lot of time in a large file.
