Description
I have a java file that over 10000 lines, everytime code Intellisense/autocomplete about this class, it would take a long time (over 10 seconds ) to show the suggestion.
eclipse is fast in the same situation.
I tried to delete most of the code in that file, and code Intellisense/autocomplete is much faster.
Is there any way to speed up the parsing of large files?

Research direction
Reproduce the delay with a Java file larger than 10,000 lines in the reported Windows 10, WSL2, JDK 11, and VS Code environment. Start by profiling autocomplete and parsing in the Java extension; done means suggestions appear without the reported delay of over 10 seconds.
