perf: reduce memory usage with caching and heap limit#665
Conversation
- Add val/var to definitionPattern regex for definition lookup - Allow build/generated-src directory by excluding specific build outputs instead of entire build directory This fixes go-to-definition failing for generated code like jOOQ Tables.kt
- Set initial heap to 256MB, max heap to 2GB - Use G1GC for better memory management - Enable string deduplication to reduce memory footprint This prevents the language server from consuming 3GB+ of memory
- Reduce default heap from 2GB to 1GB - Expand decompiled class LRU cache (5→50) to reduce repeated decompilation - Add in-memory cache layer to CachedClassPathResolver to avoid repeated DB transactions - Enable SQLite WAL mode and NORMAL synchronous for better I/O performance
