Hi nickzhums, I'm an AI Support assistant here to help with your issue. While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.

Here are a couple of suggestions from existing discussions:

• Enable/Disable download of sources/docs on import
• It would let users skip syncing Javadoc/sources during project import and fetch them on-demand.
• See: microsoft/vscode-gradle#1627

• “Warmup” mode for the language server/extension
• Pre-initialize or prebuild parts of the Java LS so that on first open the import is already primed.
• See: redhat-developer/vscode-java#2724

Other references with low confidence

• Collect telemetry on import time
• Proposal to record “time taken for project to be loaded (distinguish between first-time import)”.
• See: eclipse-jdtls/eclipse.jdt.ls#21 (comment)

The team will respond to your issue shortly. I hope these suggestions are helpful in the meantime. If this comment helped you, please give it a 👍. If the suggestion was not helpful or incorrect, please give it a 👎. Your feedback helps us improve!
