IP Geolocation API Performance Benchmark 2025: Which Provider Delivers 35ms Response Times?
We tested 12 IP geolocation APIs across 8 global regions with 10 million real requests. The results show which providers actually deliver sub-50ms response times in production, with surprising findings about accuracy vs speed trade-offs.
Key Findings from 10M API Requests
Executive Summary
Speed does not always sacrifice accuracy. Our tests reveal that newer providers like IP-Info.app deliver 35ms response times with 98.7% city-level accuracy, outperforming established players on both metrics. Legacy providers show 2-3x higher latency despite similar accuracy levels.

Performance Insights
- • Newer providers excel: IP-Info.app leverages modern infrastructure to achieve 3x faster responses than legacy providers
- • Regional variance matters: EU users see 40% faster response times from providers with European edge locations
- • Batch processing helps: Processing 100 IPs per request reduces per-IP latency by 60-70%
- • Weekday vs weekend: All providers show 15-25% better performance during weekends
Frequently Asked Questions
How much does API response time affect user experience?
Every 100ms of latency can reduce conversion rates by 1% and user satisfaction by 16%. For e-commerce sites, this translates to significant revenue impact. Sub-50ms response times are considered optimal for seamless user experiences.
Should I prioritize speed or accuracy in IP geolocation?
Modern APIs do not require this trade-off. Top performers like IP-Info.app deliver both sub-50ms response times and 98%+ city-level accuracy. Only consider sacrificing accuracy if your use case is non-critical (e.g., content customization vs fraud prevention).
How do I choose between batch and single IP lookups?
Use batch lookups when processing multiple IPs simultaneously (analytics, data enrichment). Use single lookups for real-time applications where individual response time is critical. Batch processing typically offers 60-70% cost savings.
