High memory usage

[mxl]

I run gulp-favicons with these options:

gulp.src('icon.png')
.pipe(favicons({
        appName: 'My App',
        display: 'standalone',
        orientation: 'portrait',
        version: '1.0.0',
        path: 'favicons/',
        url: 'http://example.com/,
        html: 'index.html',
        replace: true,
        icons: {
            android: true,
            appleIcon: true,
            appleStartup: true,
            coast: true,
            favicons: true,
            firefox: true,
            opengraph: true,
            twitter: true,
            windows: true,
            yandex: true
        }
    }))

icon.png has 2048x2048 size.
My machine has 2GB memory and 2GB swap. Favicons generation takes 40 seconds and often fails because there is no free memory and system kills the process.

Why memory consumption is so high and what optimizations could I apply?

@mxl Your image should be a maximum of 1500x1500 - the size of the OpenGraph image. Anything above that is overkill. Other than that, I have no idea. Perhaps there are code optimisations to be done.

Got the same issue just now. When the favicon generation starts, memory fills up really fast and process is killed by the kernel. icon.png is 1024x1024 with offline generation. Online seems to be working fine.

Not sure there's much I can do about it. I get around this on my remote SSD with 2GB of RAM by creating a massive swapfile. Online generation is done on the RFG servers so it's a valid workaround but you get a slightly different result. Not sure what I can do about this for now, it's just a memory-intense module.

Looks like an issue with Jimp jimp-dev/jimp#153
