startup time of 6.9 sec, how can I setup lazy loading

Hello
How could reduce the startup time with lazy loading ?
This configuration is already lazily loaded, and normally shouldn't take that long to start. However, the default is to use desktop-save-mode
, which causes buffers to be restored after a restart, and that can lead to slower startup times. Probably you just want to disable that, but I personally find it a better default. Take a look at init-sessions.el
.
I also notice the same issue. On my MacBook Pro 2019 , it take about 6s to startup.
And the report with sanityinc/require-time
show this:
nixos-options 2576.291
init-exec-path 380.430
init-elpa 377.706
tablist-filter 324.063
semantic/wisent/comp 302.622
semantic/wisent 277.143
semantic 222.996
lisp-mnt 219.302
mail-parse 189.951
etags 137.407
init-gui-frames 134.873
semantic/tag 119.670
package-lint 113.323
compile 106.392
rfc2231 103.094
It is cause by the nixos-options
@wereket Cool, I'll stick with this one though.
@Eason0210 Thanks for checking require-times
: yeah, I see the same behaviour. The company backend for nixos options is loaded, and then that causes nixos-options.el
to be initialized, which runs a ~2s shell command. I'll probably just drop that backend, or only register it after nix-mode
has been loaded.
Only register it after nix-mode
has been loaded would be a good option.
I also using nix on Mac, and nixos-options.el
works well recently.
Done. Now, with an empty session (no buffers) to restore:
init completed in 1674.07ms
which I think is pretty reasonable.
