Performance

Cache management strategies for high-traffic directories: TTL tuning, cache invalidation logic, CDN integration, and handling real-time listing updates.

Using CDNs to serve directory content faster: geographic distribution, image optimisation pipelines, cache-control headers, and handling dynamic listing data.

Performance optimisation techniques for directory databases: slow query analysis, connection pooling, read replica setup, and caching layers that cut load times.

Load time optimisation for directory pages: critical render path analysis, font subsetting, third-party script audit, and the metrics that correlate with ranking improvement.
