[PERFORMANCE]

[arthurafsem-del]

Performance Issue Type

• Slow command detection/generation
• Extension feels sluggish
• High CPU usage
• High memory usage
• Long startup time
• File parsing taking too long
• Override resolution slow

Description

What feels slow: [e.g., pressing Cmd+R, opening override dialog, etc.]
Expected duration: [e.g., < 1 second]
Actual duration: [e.g., 5-10 seconds]

Performance Data

Timing Information

# Run with timing: time raz "/path/to/file.rs:line:column"
[paste timing output]

System Resources

CPU Usage: [e.g., 80% for 10 seconds]
Memory Usage: [e.g., 500MB RAM]
Disk Usage: [e.g., high I/O during operation]

VS Code Performance

Extension Host CPU: [Check VS Code's Developer Tools]
Extension Memory: [Check VS Code's process explorer]

Project Information

Project size:

• Files: [approximate number of .rs files]
• Lines of code: [approximate]
• Dependencies: [number in Cargo.toml]
• Workspace members: [if applicable]

Project type: [Cargo workspace, large monorepo, many dependencies, etc.]

Cargo.toml (dependencies section)

[dependencies]
[paste dependencies - especially if many/large ones]

Reproduction Steps

1. [Steps to reproduce the slow behavior]
2. [Be specific about timing]

Environment

• OS: [e.g., macOS 14.5, Ubuntu 22.04, Windows 11]
• Hardware: [e.g., M1 Mac, Intel i7, 16GB RAM]
• Raz Version: [Run raz --version]
• VS Code Version: [if applicable]
• Rust toolchain: [Run rustc --version]

Debug Information

With verbose logging:

# Output of: time RUST_LOG=debug raz "/path/to/file.rs:line:column"
[paste output focusing on timing information]

Profile information:

# Any profiling data if available

Expected Performance

Expected behavior: [e.g., Command detection should be < 1 second]
Comparison: [e.g., "Other similar tools take X seconds"]

Additional Context

• When did this start: [Always slow, recent regression, specific project]
• Workarounds: [Anything that makes it faster]
• Pattern: [Consistent slow, gets slower over time, first run slow, etc.]
