You may want to checkout my projects:

• Ccache is a multi-language client-side caching library.

  Ccache explores ways to pull caches from remote servers to local and uses Rust to support different languages, such as Ruby and Go (in development).

• SDB is a Ruby stack profiler without GVL.

  SDB releases the GVL to avoid blocking application execution and its scanner offloads unnecessary work to improve performance.

• otel-snitch shares memory between the otel-rb client and the otel-collector to reduce RPC costs.

  otel-snitch is an experimental project aimed at avoiding serialization and network costs when the otel-client and otel-collector are on the same machine by using shared memory directly.

• Others

  • cpu-time is a simple Ruby Gem for measuring CPU time.
  • elder-wand/https is an experimental project for capturing HTTPS plaintext without a CA certificate and root right using Dylib injection.
