From 7fdea2a28582c2667c3e997e9f5c166857142192 Mon Sep 17 00:00:00 2001 From: chamiakJ Date: Mon, 30 Jun 2025 07:48:32 +0530 Subject: [PATCH] feat(performance): implement extensive performance optimizations across task management components - Introduced batching and optimized query handling in SQL functions for improved performance during large updates. - Enhanced task sorting functions with batching to reduce load times and improve responsiveness. - Implemented performance monitoring utilities to track render times, memory usage, and long tasks, providing insights for further optimizations. - Added performance analysis component to visualize metrics and identify bottlenecks in task management. - Optimized drag-and-drop functionality with CSS enhancements to ensure smooth interactions and reduce layout thrashing. - Refined task row rendering logic to minimize DOM updates and improve loading behavior for large lists. - Introduced aggressive virtualization and memoization strategies to enhance rendering performance in task lists. --- worklenz-backend/database/sql/4_functions.sql | 140 +++++++- .../commands/on-task-sort-order-change.ts | 244 ++++++++------ .../task-management/drag-drop-optimized.css | 149 +++++++++ .../task-management/performance-analysis.tsx | 284 ++++++++++++++++ .../task-management/task-list-board.tsx | 169 ++++++---- .../task-management/task-row-optimized.css | 180 +++++++---- .../components/task-management/task-row.tsx | 234 +++++--------- .../task-management/virtualized-task-list.tsx | 175 ++++++---- .../src/utils/debug-performance.ts | 284 ++++++++++++++++ .../src/utils/performance-monitor.ts | 304 ++++++++++++++++++ .../src/utils/performance-optimizer.ts | 297 +++++++++++++++++ 11 files changed, 2003 insertions(+), 457 deletions(-) create mode 100644 worklenz-frontend/src/components/task-management/drag-drop-optimized.css create mode 100644 worklenz-frontend/src/components/task-management/performance-analysis.tsx create mode 100644 worklenz-frontend/src/utils/debug-performance.ts create mode 100644 worklenz-frontend/src/utils/performance-monitor.ts create mode 100644 worklenz-frontend/src/utils/performance-optimizer.ts diff --git a/worklenz-backend/database/sql/4_functions.sql b/worklenz-backend/database/sql/4_functions.sql index 9c9cc820..fb551450 100644 --- a/worklenz-backend/database/sql/4_functions.sql +++ b/worklenz-backend/database/sql/4_functions.sql @@ -4325,6 +4325,7 @@ DECLARE _from_group UUID;
