Build crates.io

vim-profiler is a wrapper around the (n)vim --startuptime command, written in Rust. The binary is called vp and has only been tested on a Unix based system.


Here is a quick demo showcasing the main functionality of the program.



You can install vim-profiler with the rust package manager Cargo:

$ cargo install vim-profiler

Exporting results

This utility allows for exporting results to either in a .svg file in the form of a plot or in a .csv file, where extra statistics are written.


The plot visualizes the start times of each plugin in your plugin directory. If you invoke vp with the --plot option, you will receive a plot in the form of an SVG file in the specified path that looks something like:


The CSV file contains various other useful statistics such as:

  • The average start time across all iterations
  • The median start time across all iterations
  • The standard deviation from the mean

If you invoke vp with the --export option you will receive a CSV file with the additional statistics called in the specified path that looks something like:
