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
CPU usage: 95%Response time: 30000msApplication unresponsiveJVM 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.

Matthew Jordan Matthew Jordan I've been working at a large software company named Kainos for 2 years, and mainly specialise in Platform Engineering. I regularly enjoy working on software products outside of work, and I'm a huge fan of game development using Unity. I personally enjoy Python & C# in my spare time, but I also specialise in multiple different platform-related technologies from my day job. Krishna Sai Kuncha Krishna Sai Kuncha Experienced Professional Full stack Developer with 8+ years of experience across react, python, js, ts, golang and react-native. Developed inhouse websearch tooling for AI before websearch was solved : ) Luca Liberati Luca Liberati I work on monoliths and microservices, backends and frontends, manage K8s clusters and love to design apps architecture Jacek Rozanski Jacek Rozanski Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004). Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month. What I bring to AI-built apps: - I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0 - I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture) - I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting - I integrate external services: payment providers, email systems, partner APIs, SSO/auth Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code. Based in Poland (CET timezone).

I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti. 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/ Meïr Ankri Meïr Ankri Full-stack developer specializing in React / Next.js / Node.js with 6+ years of experience.

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.
