What are common causes of latency in modern API responses, and how can they be mitigated?

Hello,

API latency often stems from database query delays, network congestion, and poor code optimization. Third-party service calls and inefficient serialization can also slow responses. To mitigate this, use caching strategies, asynchronous processing, and connection pooling. Profiling tools like Postman or New Relic can help pinpoint slow paths. Also, consider rate limiting and load balancing to manage traffic efficiently. Optimizing both backend logic and infrastructure is key to minimizing lag and improving user experience.
