This benchmarks the php-vips image processing module against imagick and
gd.
The test is a very simple one:
- Load a 5,000 x 5,000 pixel JPEG image.
- Crop 100 pixels from every edge.
- Shrink by 10% using a bilinear interpolator.
- Sharpen with a 3x3 convolution
- Save back as a new JPEG image.
This is not a complex test, but it is easy to implement and does exercise image load, save, resample and filter.
The vips website has this same test performed in many different image processing systems, with some discussion:

Run on 17/8/23 with libvips 8.14, libgd 2.3.3, imagick 3.7 on Ubuntu 23.04 with a 3955WX.
