@claude-flow/plugin-performance-optimizer


A comprehensive performance optimization plugin combining sparse inference for efficient trace analysis with graph neural networks for dependency chain optimization. The plugin enables intelligent bottleneck detection, memory leak identification, N+1 query detection, and bundle size optimization while providing explainable recommendations based on historical performance patterns.

Features

- Bottleneck Detection: Identify performance bottlenecks using GNN-based dependency analysis
- Memory Analysis: Detect memory leaks, retention chains, and GC pressure points
- Query Optimization: Detect N+1 queries, missing indexes, and slow joins
- Bundle Optimization: Analyze and optimize JavaScript bundle size with tree shaking and code splitting
- Configuration Optimization: Learn optimal configurations from workload patterns using SONA

Quick Start

`typescript
import { PerfOptimizerPlugin } from '@claude-flow/plugin-performance-optimizer';

// Initialize the plugin
const plugin = new PerfOptimizerPlugin();
await plugin.initialize();

// Detect performance bottlenecks
const bottlenecks = await plugin.detectBottlenecks({
traceData: {
format: 'otlp',
spans: traceSpans,
metrics: performanceMetrics
},
analysisScope: ['cpu', 'memory', 'database'],
threshold: {
latencyP95: 500, // 500ms
throughput: 1000,
errorRate: 0.01
}
});

console.log('Detected bottlenecks:', bottlenecks);
`

MCP Tools

$3

Detect performance bottlenecks using GNN-based dependency analysis.

`typescript
// Example usage via MCP
const result = await mcp.call('perf/bottleneck-detect', {
traceData: {
format: 'chrome_devtools',
spans: chromeTraceSpans,
metrics: { renderTime: 150, scriptTime: 200 }
},
analysisScope: ['cpu', 'render', 'network'],
threshold: {
latencyP95: 100,
throughput: 60
}
});
`

Returns: List of identified bottlenecks with severity, location, and recommended fixes.

$3

Analyze memory usage patterns and detect potential leaks.

`typescript
const result = await mcp.call('perf/memory-analyze', {
heapSnapshot: '/path/to/heap-snapshot.heapsnapshot',
timeline: memoryTimelineData,
analysis: ['leak_detection', 'retention_analysis', 'gc_pressure'],
compareBaseline: '/path/to/baseline-snapshot.heapsnapshot'
});
`

Returns: Memory analysis report with leak candidates, retention chains, and optimization suggestions.

$3

Detect N+1 queries and suggest database optimizations.

`typescript
const result = await mcp.call('perf/query-optimize', {
queries: [
{ sql: 'SELECT * FROM users WHERE id = ?', duration: 5, resultSize: 1 },
{ sql: 'SELECT * FROM orders WHERE user_id = ?', duration: 3, resultSize: 10 }
],
patterns: ['n_plus_1', 'missing_index', 'slow_join'],
suggestIndexes: true
});
`

Returns: Detected query anti-patterns with suggested batch alternatives and index recommendations.

$3

Analyze and optimize JavaScript bundle size.

`typescript
const result = await mcp.call('perf/bundle-optimize', {
bundleStats: '/path/to/webpack-stats.json',
analysis: ['tree_shaking', 'code_splitting', 'duplicate_deps', 'large_modules'],
targets: {
maxSize: 250, // 250KB
maxChunks: 10
}
});
`

Returns: Bundle analysis with optimization recommendations for tree shaking, code splitting, and dependency deduplication.

$3

Suggest optimal configurations based on workload patterns using SONA learning.

`typescript
const result = await mcp.call('perf/config-optimize', {
workloadProfile: {
type: 'api',
metrics: { requestsPerSecond: 1000, avgLatency: 50 },
constraints: { maxMemory: '4GB', maxCpu: 4 }
},
configSpace: {
poolSize: { type: 'number', range: [10, 100], current: 25 },
cacheSize: { type: 'number', range: [100, 1000], current: 200 }
},
objective: 'latency'
});
`

Returns: Optimized configuration values with expected performance improvements.

Configuration Options

`typescript
interface PerfOptimizerConfig {
// WASM memory limit (default: 2GB)
memoryLimit: number;

// Analysis timeout in seconds (default: 300)
analysisTimeout: number;

// Enable SONA learning for configuration optimization
enableSONALearning: boolean;

// Supported trace formats
supportedFormats: ('otlp' | 'chrome_devtools' | 'jaeger' | 'zipkin')[];

// Performance thresholds for alerting
thresholds: {
latencyP95: number;
throughput: number;
errorRate: number;
};
}
`

Performance Targets

| Metric | Target | Improvement vs Baseline |
|--------|--------|------------------------|
| Trace analysis (1M spans) | <5s | 24x faster |
| Memory analysis (1GB heap) | <30s | 10x faster |
| Query pattern detection (10K queries) | <1s | 600x faster |
| Bundle analysis (10MB) | <10s | 6x faster |
| Config optimization | <1min convergence | 1440x+ faster |

Security Considerations

- Trace Data Sanitization: Automatically sanitizes sensitive data (passwords, tokens, cookies) from trace data before processing
- Query Parse-Only: SQL queries are parsed and analyzed but never executed
- WASM Sandboxing: All analysis runs in isolated WASM sandbox with 2GB memory limit and no network access
- Path Validation: Bundle stats paths are validated to prevent path traversal attacks
- Input Validation: All inputs validated with Zod schemas to prevent injection attacks
- No Code Execution: Performance suggestions are recommendations only - no automatic code modification

$3

| Constraint | Value | Rationale |
|------------|-------|-----------|
| Memory Limit | 2GB max | Handle large trace datasets |
| CPU Time Limit | 300 seconds | Allow deep performance analysis |
| No Network Access | Enforced | Prevent data exfiltration |
| No File System Write | Enforced | Read-only analysis mode |
| Sandboxed Paths | Validated prefixes only | Prevent path traversal |

$3

| Input | Limit |
|-------|-------|
| Max spans per trace | 1,000,000 |
| Max query size | 10KB |
| Max queries per batch | 10,000 |
| Max heap snapshot size | 1GB |
| Max bundle stats size | 50MB |
| CPU time limit | 300 seconds |
