API - Performance & Reliability
Infrastructure Optimization
Production Performance Improvements (100-500x faster queries): We've rolled out significant performance enhancements to our API v3 infrastructure. These improvements deliver dramatically faster response times and better reliability during high-traffic periods.
What you'll notice:
- Faster API responses - Most requests now complete in under 200ms (previously 2-5 seconds)
- Better concurrent request handling - API can handle more simultaneous requests without slowdowns
- More reliable service - Enhanced throttling protects against traffic spikes
Technical improvements:
- Added database optimizations for faster queries
- Expanded connection pool capacity (3x increase)
- Implemented API throttling (200 burst, 100 req/sec)
Impact: 95-98% improvement in API response times across all endpoints.
See the API requests limits section in the Cosmic docs.
Dashboard
Dashboard Performance Optimizations
2-3x Faster Page Loads: We've optimized the dashboard application for significantly improved performance and responsiveness. These enhancements provide a smoother, more efficient experience across all dashboard features.
What you'll notice:
- Faster page loads - Dashboard pages now load 2-3x faster
- More responsive UI - Instant feedback on clicks and interactions
- Smoother navigation - Reduced lag when switching between sections
- Improved data rendering - Faster content lists and object displays
Impact: Overall dashboard experience is noticeably faster and more fluid, reducing friction in your daily content management workflows.
Deployment Access Logs
View HTTP access logs (runtime logs) for your deployments directly in the dashboard. Monitor traffic, track request patterns, and debug production issues with detailed logging including:
- Request method, path, status, and duration
- Client IP and user agent information
- Deployment metadata and region information
- Project-level aggregated logs across multiple deployments
Access logs support pagination, filtering by timestamp, methods, and live mode for real-time request monitoring.
