Performance Optimization Guide

Comprehensive guide for optimizing NeuroLink performance, reducing latency, and maximizing throughput in production environments.

🚀 Quick Performance Wins

Immediate Optimizations

  1. Enable Response Caching

    const neurolink = new NeuroLink({
  caching: {
    enabled: true,
    ttl: 300000, // 5 minutes
    maxSize: 1000,
  },
});

  2. Use Streaming for Long Responses

    const stream = await neurolink.stream({
  input: { text: "Write a comprehensive report..." },
  provider: "anthropic",
});

for await (const chunk of stream) {
  console.log(chunk.content); // Process immediately
}

  3. Implement Request Batching

    # CLI batch processing
npx @juspay/neurolink batch process \
  --input prompts.txt \
  --output results.json \
  --parallel 3

📊 Performance Monitoring

Real-time Metrics

import { NeuroLink, PerformanceMonitor } from "@juspay/neurolink";

const neurolink = new NeuroLink({
  monitoring: {
    enabled: true,
    metricsInterval: 30000, // 30 seconds
    trackLatency: true,
    trackThroughput: true,
    trackErrors: true,
  },
});

// Get performance insights
const monitor = new PerformanceMonitor(neurolink);
const metrics = await monitor.getMetrics();

console.log("Average Response Time:", metrics.averageLatency);
console.log("Requests per Second:", metrics.throughput);
console.log("Error Rate:", metrics.errorRate);

Performance Dashboard

// Setup real-time performance dashboard
const dashboard = new PerformanceDashboard({
  refreshInterval: 5000, // 5 seconds
  metrics: [
    "response_time",
    "throughput",
    "cache_hit_ratio",
    "provider_health",
    "error_rate",
    "token_usage",
  ],
});

await dashboard.start();

⚡ Provider Optimization

Provider Selection Strategy

// Intelligent provider routing
const neurolink = new NeuroLink({
  routing: {
    strategy: "performance_optimized",
    criteria: {
      latency: 0.4, // 40% weight
      reliability: 0.3, // 30% weight
      cost: 0.2, // 20% weight
      quality: 0.1, // 10% weight
    },
  },
});

Response Time Optimization

// Provider-specific timeouts
const optimizedConfig = {
  providers: {
    openai: { timeout: 15000 }, // Fast for simple tasks
    anthropic: { timeout: 30000 }, // Balanced
    bedrock: { timeout: 45000 }, // Longer for complex reasoning
  },
};

Load Balancing

// Multi-provider load balancing
const loadBalancer = new ProviderLoadBalancer({
  providers: ["openai", "anthropic", "google-ai"],
  algorithm: "least_loaded",
  healthChecks: {
    interval: 30000,
    timeout: 5000,
    failureThreshold: 3,
  },
});

🔧 Advanced Configuration

Connection Pooling

const neurolink = new NeuroLink({
  connectionPool: {
    maxConnections: 20,
    keepAlive: true,
    maxIdleTime: 30000,
    retryOnFailure: true,
  },
});

Request Optimization

// Optimize token usage
const optimizedRequest = {
  input: { text: prompt },
  maxTokens: calculateOptimalTokens(prompt),
  temperature: 0.7,
  stopSequences: ["---", "END"],
  truncateInput: true,
  compressHistory: true,
};

Parallel Processing

// Parallel request processing
async function processInParallel(prompts: string[]) {
  const chunks = chunkArray(prompts, 5); // Process 5 at a time

  for (const chunk of chunks) {
    const promises = chunk.map((prompt) =>
      neurolink.generate({ input: { text: prompt } }),
    );

    const results = await Promise.allSettled(promises);
    processResults(results);
  }
}

🎥 Video Generation Performance Optimization

Video generation via Veo 3.1 requires special performance considerations due to longer processing times and larger resource requirements.

Timeout Configuration

Video generation typically takes 1-3 minutes. Configure appropriate timeouts:

import { NeuroLink } from "@juspay/neurolink";

const neurolink = new NeuroLink();

const result = await neurolink.generate({
  input: {
    text: "Product showcase video",
    images: [imageBuffer],
  },
  provider: "vertex",
  model: "veo-3.1",
  output: { mode: "video" },
  timeout: 180, // 3 minutes (recommended minimum)
});

Polling Strategy

Video generation uses long-polling. Optimize the polling strategy:

// Adjust polling intervals for better performance
const result = await neurolink.generate({
  input: { text: "Video prompt", images: [image] },
  provider: "vertex",
  model: "veo-3.1",
  output: {
    mode: "video",
    video: {
      resolution: "720p", // Use 720p for faster generation
      length: 4, // Shorter videos generate faster (4s vs 8s)
    },
  },
  // Custom polling configuration (if supported)
  pollInterval: 5000, // Check every 5 seconds
  maxPolls: 36, // Up to 3 minutes (36 * 5s)
});

Resource Optimization

Resolution vs Speed Trade-off:

Resolution Avg Time File Size Use Case
720p 60-90s ~5-10MB Social media, previews
1080p 90-180s ~15-30MB Professional content, demos

Length vs Speed Trade-off:

Length Avg Time Use Case
4s 60-90s Quick animations, teasers
6s 75-120s Social media posts
8s 90-180s Product showcases, storytelling

Batch Processing Strategy

Process multiple videos efficiently:

import { NeuroLink } from "@juspay/neurolink";
import PQueue from "p-queue";

const neurolink = new NeuroLink();

// Limit concurrent video generations (Vertex AI rate limits)
const queue = new PQueue({ concurrency: 2 });

async function generateVideos(requests: VideoRequest[]) {
  const results = await Promise.allSettled(
    requests.map((req) =>
      queue.add(async () => {
        try {
          return await neurolink.generate({
            input: { text: req.prompt, images: [req.image] },
            provider: "vertex",
            model: "veo-3.1",
            output: {
              mode: "video",
              video: {
                resolution: req.resolution || "720p",
                length: req.length || 6,
              },
            },
            timeout: 180,
          });
        } catch (error) {
          console.error(`Failed to generate video: ${req.id}`, error);
          return null;
        }
      }),
    ),
  );

  return results.filter((r) => r.status === "fulfilled" && r.value !== null);
}

Caching Strategy

Video generation is expensive. Implement aggressive caching:

import { createHash } from "crypto";
import { readFile, writeFile, access } from "fs/promises";

// Generate cache key from inputs
function getCacheKey(prompt: string, imageBuffer: Buffer): string {
  const hash = createHash("sha256");
  hash.update(prompt);
  hash.update(imageBuffer);
  return hash.digest("hex");
}

async function generateVideoWithCache(prompt: string, image: Buffer) {
  const cacheKey = getCacheKey(prompt, image);
  const cacheFile = `./cache/videos/${cacheKey}.mp4`;

  // Check cache first
  try {
    await access(cacheFile);
    const cached = await readFile(cacheFile);
    console.log("✅ Video served from cache");
    return { video: { data: cached }, cached: true };
  } catch {
    // Not in cache, generate new
  }

  const neurolink = new NeuroLink();
  const result = await neurolink.generate({
    input: { text: prompt, images: [image] },
    provider: "vertex",
    model: "veo-3.1",
    output: { mode: "video" },
  });

  // Cache the result
  if (result.video) {
    await writeFile(cacheFile, result.video.data);
    console.log("✅ Video cached for future use");
  }

  return { ...result, cached: false };
}

Cost Optimization

Best Practices:

  1. Use 720p by default - 30-50% faster, 60% lower cost
  2. Prefer 4-6 second videos - Faster generation, lower cost
  3. Implement aggressive caching - Avoid regenerating identical videos
  4. Batch similar requests - Group by resolution/length for efficiency
  5. Monitor Vertex AI quotas - Set up alerts before hitting limits

Cost Comparison:

Configuration Avg Time Relative Cost Best For
720p, 4s, no audio 60s 1x Quick previews
720p, 6s, audio 90s 1.5x Social media
1080p, 8s, audio 180s 3x Professional content

Error Handling for Long Operations

import { NeuroLink } from "@juspay/neurolink";

async function robustVideoGeneration(prompt: string, image: Buffer) {
  const neurolink = new NeuroLink();
  const maxRetries = 2;
  let attempt = 0;

  while (attempt < maxRetries) {
    try {
      const result = await neurolink.generate({
        input: { text: prompt, images: [image] },
        provider: "vertex",
        model: "veo-3.1",
        output: { mode: "video" },
        timeout: 180,
      });

      return result;
    } catch (error) {
      attempt++;

      if (error.code === "VIDEO_POLL_TIMEOUT" && attempt < maxRetries) {
        console.log(`Timeout on attempt ${attempt}, retrying...`);
        continue;
      }

      if (error.code === "VIDEO_QUOTA_EXCEEDED") {
        console.error("Quota exceeded. Wait before retrying.");
        throw error;
      }

      throw error;
    }
  }

  throw new Error("Video generation failed after maximum retries");
}

Monitoring Video Generation Performance

type VideoMetrics = {
  totalGenerated: number;
  avgGenerationTime: number;
  cacheHitRate: number;
  failureRate: number;
  costEstimate: number;
};

class VideoPerformanceMonitor {
  private metrics: VideoMetrics = {
    totalGenerated: 0,
    avgGenerationTime: 0,
    cacheHitRate: 0,
    failureRate: 0,
    costEstimate: 0,
  };

  recordGeneration(duration: number, cached: boolean, success: boolean) {
    this.metrics.totalGenerated++;

    if (!cached && success) {
      // Update average generation time
      const total =
        this.metrics.avgGenerationTime * (this.metrics.totalGenerated - 1);
      this.metrics.avgGenerationTime =
        (total + duration) / this.metrics.totalGenerated;
    }

    // Update cache hit rate
    const cacheHits =
      this.metrics.cacheHitRate * (this.metrics.totalGenerated - 1);
    this.metrics.cacheHitRate =
      (cacheHits + (cached ? 1 : 0)) / this.metrics.totalGenerated;

    // Update failure rate
    const failures =
      this.metrics.failureRate * (this.metrics.totalGenerated - 1);
    this.metrics.failureRate =
      (failures + (success ? 0 : 1)) / this.metrics.totalGenerated;
  }

  getMetrics(): VideoMetrics {
    return { ...this.metrics };
  }
}
