Sample AI Analysis · WPLoadTester 7
Frontend Performance Trend Analysis
A sample AI analysis comparing the same server's load tests across six years — 2019, 2020, and 2025 — and picking the best performer. As a site is modified year after year, this is how you tell whether its capacity and performance are trending faster or slower than before.
What this is: this analysis was generated off the cuff by the Claude Code CLI through WPLoadTester's MCP server, pointed straight at the load tests' metrics — a quick, unscripted example. It is not the product's report. WPLoadTester 7.0's AI Bottleneck Report is the curated version: a one-click report we have tuned over years of professional engagements to cover every finding a load-test analysis should include.

Trend Analysis
Scalability Evolution Dramatically Improved
- Test 1 (2025) achieves near-perfect scalability: Response times only vary from 0.75s to 0.88s (17% variance) across entire load range
- Test 2 (2019) shows poor scalability: Degrades from 0.41s to 2.39s (483% increase) - unacceptable for production
- Test 3 (2020) exhibits catastrophic scaling: 0.59s to 5.27s (793% increase) plus 679 failures
- Area under the curve: Test 1 has the lowest total response time across all load levels
Architectural Evolution
- 2025 (Test 1): Flat response curve indicates modern reactive architecture, likely non-blocking I/O
- 2019 (Test 2): Good at low load but exponential degradation suggests thread-pool exhaustion
- 2020 (Test 3): Linear degradation with high failure rate indicates resource contention
Scalability Patterns
- Test 1 (2025): Linear scaling, minimal degradation - best for predictable load
- Test 2 (2019): Excellent low-load performance, exponential degradation at high load
- Test 3 (2020): Poor scalability with 8.9x degradation and high failure rate
💡 Recommendation
Clear Winner: Deploy Test 1 (July 2025) Configuration
- Flattest response curve - essentially constant performance regardless of load
- Best scalability with only 17% variance across entire load range
- Maintains sub-second response times at all load levels (0.75-0.88s)
- Lowest area under the response time curve
- Minimal failure rate (27 total failures vs 679 in Test 3)
Avoid Test 2 (2019): Despite good low-load performance (0.41s at 500 users), it degrades exponentially and reaches unacceptable 2.39s at 2000 users. The 483% degradation makes it unsuitable for variable production loads.
