anthracite/CHANGELOG.md

# 0.2.0 Fifth Pre-Release
- Added true HTTP/1.1 support with persistent connections
- Added HTTP/1.0 vs HTTP/1.1 test to benchmarking suite
- Slight improvements to benchmarking
- Added version number information to binaries at build-time
- Added error page generation build step
- GitHub CI pipeline will now tag the version when publishing the container to the registry
- General system stability improvements were made to enhance the user's experience

## HTTP/1.1 Speed improvements
The following benchmark shows the speed improvements created by implementing
persistent connections with HTTP/1.1. This test measures the time it takes to 
request a 222 byte file 10,000 times by one user 

```

Requests     : 10000
Test         : HTTP 1.0 vs HTTP 1.1


HTTP/1.0 Total Time: 3.1160 seconds
HTTP/1.1 Total Time: 0.3621 seconds
```

## Benchmark Results
Each benchmark makes 1000 requests requesting a 50MB file using 
100 users to the webserver running in a Docker container.

This is a change from previous benchmarks which used a large html
file.

# 0.1.2 Fourth Pre-Release

- Fixed bug with mapping / to index.html
- Addex Origin-Server header

# 0.1.1 Third Pre-Release

- Add mappings for common MIME types
- Heavily improved resource utilization
- Removed non-cached file backend 
- Updated dockerfile to remove build files after build

## Known Issues

- Benchmark program does not include resource utilization

## Benchmark Results

Each benchmark makes 1000 requests requesting a 21.9Mb file using 
100 users to the webserver running in a Docker container.

The results from this benchmark vary quite a bit. About half the time,
Apache can beat anthracite.
