imgproxy vs alternatives benchmark

Setup

c5.xlarge AWS instance: 4 CPUs, 8 GB RAM
Ubuntu 18.04
Go 1.12
Python 2.7
Vips 8.7.4

All the tools were launched with their default settings except the following (where applicable):

Concurrency was set to 8;
Filesystem image source was configured. Where not applicable, local nginx was used as the image source.

Benchmarking

We used Apache HTTP server benchmarking tool (a.k.a ab):

ab -n 1000 -c 4 $url

The source image is a photo of Wat Arun (JPEG, 7360x4912, 29MB).

The tools were requested to resize it to fit 500x500.
