Detect Java Microservice Bottlenecks with ARMS Code Hotspots

During high‑traffic load tests, e‑commerce services often hit performance ceilings, leading to low success rates and high latency; by combining tracing data, CPU flame‑graphs, and Alibaba Cloud’s ARMS 3.x JavaAgent features such as Code Hotspots and Adaptive Overload Protection, teams can automatically locate bottlenecks, mitigate traffic spikes, and improve stability without code changes.
