The article benchmarks three Chinese multimodal large models—Step 3.7 Flash, MiniMax M3, and Qwen 3.6‑flash—across two real‑world tasks, measuring output quality, API latency, and token cost, and concludes that Step 3.7 Flash consistently offers the best speed‑cost trade‑off for production use.
This article provides a systematic, step‑by‑step approach for identifying the root causes of slow SQL statements and sluggish API responses, covering monitoring, query analysis, index tuning, N+1 detection, caching, async processing, and architectural best practices.
This article explains why measuring API response time is crucial for performance optimization, monitoring, and user experience, and presents six practical methods—from simple System.currentTimeMillis() calls to Spring AOP, interceptors, filters, and production‑grade Micrometer/APM tools—complete with code examples, pros, cons, and suitable scenarios.
This article explains key performance metrics such as API latency, SLA commitments, and percentile indicators P90, P95, and P99, illustrating how to calculate and interpret these values along with average and maximum latency to improve system reliability and user experience.
