Requires Rust toolchain and compilation from source, which can be complex for users unfamiliar with Rust or without build tools, as installation involves cargo commands.

Primarily targets 64-bit Linux servers; support for other systems depends on epoll or kqueue, which may not be available on all platforms, limiting broader adoption.

Some features are marked as unstable according to the wiki page on feature stability, indicating potential bugs or incomplete implementations that could affect reliability.

Requires manual configuration via TOML files with defaults that may not suit all use cases, adding setup complexity compared to more plug-and-play solutions.
