Visual and interactive profiling of Emacs init process.
See this page for examples.
initchart.el provides macros and functions to measure and visualize a init
process of Emacs.
First, one need to record the execution time of some primary functions such
as load and require. Use the macro initchart-record-execution-time-of
at the beginning of your init.el to register functions of concern, and then
launch an Emacs process as usual. Execution time of the registered functions
will be logged in the *initchart* buffer.
Then, you can visualize these logs by invoking the command
initchart-visualize-init-sequence, which will ask you the filepath to save
an output SVG image.
;; Load the library
(require 'initchart)
;; Measure the execution time of a specified function for every call.
;; Optionally, you might give a parameter name of the function you specified to
;; record what value is passed to the function.
