I have had this snippet in my .zshrc for years,
autoload -U compinit && compinit
{
# Compile the completion dump to increase startup speed. Run in background.
zcompdump="${ZDOTDIR:-$HOME}/.zcompdump"
if [[ -s "$zcompdump" && (! -s "${zcompdump}.zwc" || "$zcompdump" -nt "${zcompdump}.zwc") ]]; then
# if zcompdump file exists, and we don't have a compiled version or the
# dump file is newer than the compiled file
zcompile "$zcompdump"
fi
} &!
Using `zmodload zsh/zprof`, I can see about 50% (16ms) of my start up is compinit (its about 28ms without the `zcompile`).
Do you have any pointers for the "load on tab" idea? I didn't turn up any good results in DDG and LLMs were just hallucinating.
BTW I believe `-C` will disable some cache checking, caching is enabled by default
> To speed up the running of compinit, it can be made to produce a dumped configuration that will be read in on future invocations; this is the default, but can be turned off by calling compinit with the option -D.

> ... The check performed to see if there are new functions can be omitted by giving the option -C. In this case the dump file will only be created if there isn't one already.
