Case Study: Cutting TTFB by 60% and Doubling Scrape Throughput
Hook: Real-world optimisation can dramatically improve scraper efficiency. This case study walks through a practical plan that reduced TTFB by 60% and doubled throughput without buying hardware.
Background
A mid-size data startup struggled with slow origin responses and rising cloud bills. Their goals were clear: reduce average page load time and increase successful extractions per hour.
Interventions
- Introduced an edge snapshot cache to serve repeat requests.
- Optimised DNS and reduced TLS handshake times using connection pooling.
- Moved heavy transformations off the main path into asynchronous workers.
Measurement and Instrumentation
They measured:
- TTFB per domain
- Cache hit ratios
- Extraction success rate and cost per page

CDN & Caching Choices
Choosing the right CDN and cache configuration mattered. They ran A/B tests on caching TTLs and purge strategies. For hosting large libraries of snapshots and backgrounds they benchmarked FastCacheX to validate throughput and cost: Review: FastCacheX CDN for Hosting High‑Resolution Background Libraries — 2026 Tests.
Operational Gains
- 60% reduction in average TTFB
- 2x scrape throughput using the same compute budget
- 30% reduction in repeat origin requests
Takeaways
Small changes compound:
- Edge caching delivers outsized returns for repeat queries.
- Architectural separation (sync vs async) prevents pipeline backpressure.
- Measure everything; use those metrics to tune purges and budgets.
“Optimisation is an engineering practice — instrument first, tweak second.”
Checklist for Teams
- Record baseline TTFB across representative domains.
- Introduce snapshot caching with incremental purging rules.
- Move CPU-heavy transforms into worker queues.
- Retest and iterate based on segment-level metrics.

Conclusion: Measure TTFB and make caching a first-class citizen in your scraping stack. The payoff is faster extraction, lower cost, and more reliable deliveries to your consumers.
