# 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](https://httpd.apache.org/docs/2.4/programs/ab.html) (a.k.a `ab`):
```bash
ab -n 1000 -c 4 $url
```
The source image is a [photo of Wat Arun](https://upload.wikimedia.org/wikipedia/commons/b/b7/The_sculptures_of_two_mythical_giant_demons%2C_Thotsakan_and_Sahatsadecha%2C_guarding_the_eastern_gate_of_the_main_chapel_of_Wat_Arun%2C_Bangkok.jpg) (JPEG, 7360x4912, 29MB).
The tools were requested to resize it to fit 500x500.
