anthracite/CHANGELOG.md

0.3.0

• SSL support via OpenSSL
• Added "Thread Manager" class to allow for multiple (or custom) threading models (process per thread, event loop)
• Defaul threading model is now event loop
• Rewrote request parser for readability and speed
• Added improved logging with different log levels
• Separated anthracite into libanthracite and anthracite-bin to allow for other projects to implement anthracite (example in ./src/api_main.cpp)
• Cleaned up code and seperated most code into headers & source
• Revamped build system to use CMake properly
• Moved CI/CD over to Forgejo
• General system stability improvements were made to enhance the user's experience

HTTP Request Parser Rewrite

The following benchmark (source in ./tests/speed_tests.cpp) shows the speed improvements made between 0.2.0 and 0.3.0, as well as comparison to boost's parsing library.

It should probably be noted that Boost's parser can do a lot more than mine and is likely slower for good reason. Also, these were single runs but subsequent runs showed similar results.

Parser Tested	RPS
Anthracite 0.2.0	688,042
Anthracite 0.3.0	27,027,000
Boost Beast	1,023,230

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

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.
