Research direction

The report names no project file, entry point, or test. Start by reproducing completion with three-letter input in a 5,000-line Java file and compare it with a small file and VS Code; done means the large-file latency is diagnosed and measurably improved or the limitation is documented.

Description

performance

Hi, I found that code completion on large java (say 5000 lines) file is extremely slow, when I enter three letter Lis, I expect it popup the candidates, it is very slow, many times unsuccessful. Do you have the same experience? Any suggestion? Thanks!

This isn't a problem on small java file.
This isn't a problem to VS Code. Maybe there is room for improvement.
