Input Schema

{
  "type": "object",
  "properties": {
    "projectPath": { "type": "string" },
    "framework": { "enum": ["electron", "tauri", "native"] },
    "iterations": { "type": "number", "default": 5 }

}

Electron Startup Profiling

// Add to main.js
const startTime = Date.now();

app.on('ready', () => {
  console.log(`App ready: ${Date.now() - startTime}ms`);
});

// Enable tracing
app.commandLine.appendSwitch('trace-startup');
app.commandLine.appendSwitch('trace-startup-file', 'startup-trace.json');

Optimization Techniques

Lazy load modules
Defer non-critical initialization
Optimize bundle size
Use V8 snapshots
Preload critical resources
