rssh

Usage

# Install `rssh` binary in your CARGO path.
$ cargo install --path .

# Initializes and hardlinks all the mini utility `cmd` binaries to the shell.
$ rssh

# Run any of the commands in the rssh/src/cmd/ directory.
$ <cmd>

Profiling

cargo flamegraph

Use cargo flamegraph to build and profile a Rust project by specifying the --build and --profile options.

For example:

cargo flamegraph --build --profile=release --bin <binary_name>

This will compile the project in release mode, profile the specified binary and generate a flamegraph for it. The flamegraph will help you visualize the performance of the program by showing the hotspots in the code, where most of the time is spent.

perf

First, make sure the release build of the program has debugging information enabled by adding the following to the Cargo.toml file:

[profile.release]
debug = true

or set the environment variable:

export CARGO_PROFILE_RELEASE_DEBUG=true

Build the program in release mode:

cargo build --release

Use perf record to capture performance data:

perf record -g --call-graph dwarf target/release/rssh

Use perf report to analyze the performance data:

perf report

This will give a detailed report of the performance of the program and help identify performance bottlenecks.
