Optimize Shiny Performance

Profile, diagnose, and optimize Shiny application performance through caching, async operations, and reactive graph optimization.

When to Use

• Shiny app feels slow or unresponsive during user interaction
• Server resources are exhausted under concurrent user load
• Specific operations (data loading, plotting, computation) create bottlenecks
• Preparing an app for production deployment with many users

Inputs

• Required: Path to the Shiny application
• Required: Description of the performance problem (slow load, laggy interaction, high memory)
• Optional: Number of expected concurrent users
• Optional: Available server resources (RAM, CPU cores)
• Optional: Whether the app uses a database or external API
