setConcurrentDaemons()

​

Syntax

OpenComicAI.setConcurrentDaemons(count?: number): void

​

Parameters

​

Returns

​

Behavior

• Limits the number of upscaling processes running at the same time
• When the limit is reached, older idle daemons are closed automatically
• Higher values allow more parallel processing but consume more memory
• Lower values reduce memory usage but may slow down batch processing

​

Example

import OpenComicAI from '@opencomic/ai-bin';

// Allow up to 5 concurrent daemons
OpenComicAI.setConcurrentDaemons(5);

// Process multiple images (up to 5 will run in parallel)
const images = ['image1.jpg', 'image2.jpg', 'image3.jpg', /* ... */];

for (const image of images) {
  await OpenComicAI.upscale({
    input: image,
    output: `upscaled-${image}`,
    daemonMode: true
  });
}

​

Performance considerations

​

High concurrency (5-10 daemons)

• Faster batch processing
• Higher memory usage (1-2GB per daemon)
• Best for systems with abundant RAM

​

Low concurrency (1-2 daemons)

• Lower memory footprint
• Sequential or limited parallel processing
• Better for resource-constrained systems

​

Default (3 daemons)

• Balanced approach
• Good for most use cases
