Shot Table Performance Test

Performance Optimizations Applied

• ✅ Used shallowRef for columns to avoid deep reactivity
• ✅ Added markRaw to column definitions to prevent Vue reactivity
• ✅ Added stable keys to EditableTaskStatus components
• ✅ Debounced column visibility updates
• ✅ Memoized column creation to only recreate when dependencies change

Expected Performance Improvements

Manual Testing Instructions

1. Navigate to a project's shots page in table view
2. Ensure there are multiple shots with task columns visible
3. Click the "Show/Hide Tasks" button in the toolbar
4. Measure the response time
5. Verify that task columns toggle quickly (< 500ms)

Technical Details

Key Changes Made:

• ShotBrowser.vue: Replaced computed columns with shallowRef and manual updates
• columns.ts: Added stable keys to EditableTaskStatus components
• Column Visibility: Debounced updates to prevent rapid re-renders
• Reactivity: Used markRaw to prevent deep reactivity on column definitions

Performance Benefits:

• Prevents unnecessary component destruction/recreation
• Reduces Vue's reactivity overhead on large objects
• Maintains component state during visibility changes
• Eliminates redundant API calls from component recreation

Verification Checklist

Browser Performance Tools

Use Chrome DevTools Performance tab to measure:

• Component render time
• JavaScript execution time
• DOM manipulation overhead
• Memory usage during column toggling
