indexing cost too long time (20min+)

[mozhuanzuojing]

We have four tasks blocked waiting for the index to build, and it’s extremely slow because it’s only running on one thread. How can we make this process run in parallel?

[mozhuanzuojing]

Hey, can we make the indexing run with 4 parallel workers? They shouldn’t block each other. By the way, I noticed VS Code Insiders keeps rebuilding the index on every startup.

[fbricon]

@snjeza could you please investigate?

[fbricon]

@mozhuanzuojing please enable verbose tracing ("java.trace.server":"verbose"), restart the extension and attach the logs from the Language Support for Java output view. There might be some specific config that triggers the reindexing on restart.

[mozhuanzuojing]

I know my computer’s performance is a bit weak, but here’s the real situation with the indexing: one core is on the job, while the other five are just… well, being bystanders.

[mozhuanzuojing]

@mozhuanzuojing please enable verbose tracing ("java.trace.server":"verbose"), restart the extension and attach the logs from the Language Support for Java output view. There might be some specific config that triggers the reindexing on restart.

@fbricon Quick heads-up: I’ll provide the logs later today. The indexing just finished, so I need to capitalize on this and work for a couple of hours.
