Synthetic micro benchmark of basic HTTP server against localhost, this time Crystal 1.2.1 on multiple versions of Alpine:

Hello! I'm doing some analysis of installed Ruby gems, specially those that require a compiler toolchain to be installed.
This analysis will help me determine an usage pattern and potentially work with gem authors to improve platform support for those gems.
Will be great if you can help me collect this information.
