Performance Testing With AI

TL;DR

• AI can analyze load test results, identify bottlenecks, and suggest optimizations. It's good at pattern-finding in metrics.
• Load profiles, targets, and prioritization are human decisions. AI doesn't know your SLOs or user patterns.
• Use AI to interpret results faster. Don't let it set your performance budget or decide what "good enough" means.

Performance testing generates a lot of data. AI can sift it. You decide what to do about it.

What AI Handles

• Bottleneck detection. "Latency spikes correlate with DB connection pool exhaustion." AI can correlate metrics and suggest causes.
• Load profile generation. "Simulate 1000 users with 10% checkout, 30% browse." AI can draft k6 or JMeter scripts. You validate the distribution.
• Anomaly flagging. "This run had unusual p99. Here's what differed." Useful for comparing runs.
• Optimization suggestions. "Adding an index on X could reduce query time." AI has seen similar patterns. Verify before applying.
• Report summarization. "Key findings: DB is the bottleneck at 500 RPS. Recommend connection pooling." AI drafts; you validate.

What You Own

• Targets. What's acceptable? 200ms p95? 99.9% under 500ms? AI can't set business SLOs.
• Load shape. What does real traffic look like? Spikes? Steady? AI can model from data—if you have it. Otherwise, you define.
• Prioritization. We have 5 bottlenecks. Fix which first? AI might suggest by impact; you balance effort, risk, and roadmap.
• Root cause. AI suggests hypotheses. You confirm. "Connection pool" might be right—or it might be lock contention. Verify.

Integration

• Many performance tools (k6, Gatling, etc.) have AI plugins or integrations for analysis.
• Combine with APM. AI can correlate load test results with production metrics. "We saw this in load test; it's also happening in prod under similar conditions."

Do This Next

1. Run a load test with AI-assisted analysis. Compare: what did AI find vs. what you would have found manually? How much time saved?
2. Document your performance targets in one place. Use them as prompt context: "Analyze these results. Our target is p95 < 200ms. Which failures matter?"
