Windsurf performance

Cascade Generated CPU-Intensive Loop

CPU usage spikes to 100% after Cascade added new code, causing application to become unresponsive. Server cannot handle normal traffic load, and response times are terrible. Profiling shows certain methods consuming excessive CPU.

Cascade likely generated algorithms with high computational complexity or inefficient loops.

Error Messages You Might See

CPU usage: 95% Response time: 30000ms Application unresponsive JVM uses 100% CPU

Common Causes

  1. Cascade generated nested loops with O(n²) or worse complexity on large datasets
  2. Infinite loop or busy-wait logic in polling code
  3. Cascade created synchronous processing where asynchronous would be better
  4. Thread contention: too many threads competing for resources

How to Fix It

Profile application with JProfiler or async-profiler to identify hot methods. Optimize algorithms: avoid nested loops on large data. Use batch processing or pagination. Consider asynchronous processing with queues. Implement caching for repeated calculations. Check for thread contention with jstack sampling.

I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks. https://blog.vtemian.com/ Daniel Vázquez Daniel Vázquez Software Engineer with over 10 years of experience on Startups, Government, big tech industry & consulting.

Frequently Asked Questions

How do I profile CPU usage?

Use async-profiler (open-source) or commercial tools like JProfiler. Identify which methods consume time.

What's the difference between O(n) and O(n²)?

O(n²) means time doubles when data doubles. Scales poorly. For 1M items: O(n)=1M ops vs O(n²)=1 trillion ops.
