System Performance & RPS

System performance plays a critical role in the user experience of any digital platform. At LoginRadius, we prioritize low-latency, high-throughput identity services to ensure that every authentication, registration, and profile management request is processed quickly and reliably.

Our cloud-native platform is built on top of Amazon Web Services (AWS), leveraging its globally distributed infrastructure to ensure high availability and performance. With integrated Content Delivery Network (CDN) support and geographically dispersed data centers, LoginRadius minimizes latency by reducing the distance between users and services. Additionally, our single-tenant deployment option provides dedicated infrastructure for customers who require greater data isolation and control, similar to how we support clients in regulated industries, such as weather services.

This performance framework enables us to support high traffic volumes, sudden usage spikes, and enterprise-level workloads without compromising on speed or reliability.

API Rate Limits (Requests Per Second)

To maintain platform stability and ensure fair usage across all tenants, LoginRadius enforces default API rate limits. These limits define how many requests per second (RPS) an application can make, based on the environment and user volume:

EnvironmentCore API RequestsSearch Operations
Production (Up to 10M users)50 requests per second10 searches per second
Production (Over 10M users)100 requests per second50 searches per second
Development / Staging5 requests per second5 searches per second

These limits help safeguard the LoginRadius Identity Platform against misuse while preserving performance for all customers.

Need more capacity? We offer flexible scaling options to meet your business needs. Contact your LoginRadius account manager or raise a support ticket to increase your API rate limits based on traffic requirements.

Handling Rate Limits

When an application exceeds its allocated RPS threshold:

  • The API responds with a 429 HTTP status code (Too Many Requests).

  • We recommend that your application pause further API calls temporarily or implement exponential backoff using the Retry-After header (if available).

  • Monitoring API usage trends using LoginRadius' analytics tools is best to avoid reaching these limits.

Proper handling of rate limits ensures uninterrupted service for both your users and other applications sharing the platform.

Performance Optimization Features

LoginRadius implements several backend strategies to maintain optimal performance, even under load:

  • Global Proxy Network: API traffic is routed through six strategically located proxy servers across North America, Europe, and Asia. This setup ensures low-latency access by directing requests through the nearest proxy, improving performance and reliability for users worldwide.

  • Scalable Infrastructure: Our infrastructure is designed to handle typical traffic fluctuations with sufficient bandwidth. We have processes to scale resources as needed for larger traffic surges, ensuring continued performance and stability.

  • Failover and Redundancy: In the event of data center issues, requests are seamlessly rerouted to alternative regions, preventing service disruptions.

  • Smart Caching & Compression: Frequently accessed resources are cached, and responses are compressed to reduce payload size and speed up delivery.

  • Real-Time Traffic Management: Traffic patterns are monitored continuously to prevent bottlenecks and route requests through the most efficient paths.

Best Practices for Developers

To make the most of LoginRadius performance and stay within rate limits:

  • Use Caching Wisely: Cache profile data and static responses when applicable.

  • Monitor and Adapt: Use Platform Analytics to track request volume, response time, and identify trends.

  • Implement Retry Logic: Gracefully handle rate-limit errors using exponential backoff and retry headers.
