Consuming a lot of memory while processing images

[Artur-Frank]

Unfortunately I do not speak English well. therefore I am writing through a translator.
When I use sharp for image processing and turn off the cache, each image takes up memory.
Tracking memory consumption via pm2. And when I load a large image through api, it can increase memory consumption by 15-20mb.

Node: 14.11.0

const sharp = require('sharp');
sharp.cache(false);
///
await sharp(_image[0].data).jpeg({ progressive: true }).toBuffer()
                    .then(async (buffer) => {
                        await fs.writeFile(`${workspaceRoot}/public/publication_${_datetime}_user${_id}_350_350.jpeg`, await sharp(buffer).resize(350, 350).toBuffer());
                        return await fs.writeFile(`${workspaceRoot}/public/publication_${_datetime}_user${_id}_orig.jpeg`, buffer)
                    })
