chadopen is a bit slow on first run

[smartding]

The first time I run chadopen, there's delay about half a second. No delay on subsequent chadopen. I've disabled session and version control;

  vim.api.nvim_set_var("chadtree_settings", {
    session = false,
    version_control = {
      defer = true,
      enable = false
    },
  })

Is there any other tricks I can use to speed up chadopen?

[ms-jpq]

I will do a refactor soon, to make sure CHADTREE runs in its own process apart from neovim's recommended way.

might speed it up.

right now all python extensions run in the same process which is a bit dumb imo

https://github.com/ms-jpq/chadtree/pull/100

will close

I see a pretty big difference when I make it so that git is deferred too.

I will probably make it so that's the case by default

[alex-popov-tech]

hey @ms-jpq , so it should be fast now? for me its still a bit slow ( like a few seconds on small projects )

[sheluchin]

Yes, a bit slow for me as well.

[ms-jpq]

a few seconds? that sounds weird,

are you guys on the newest thingy? it should have asked you to install some stuff if you do have the new version

[alex-popov-tech]

hey, yes, i've installed chadtree couple of days ago

[mpasa]

For me, it's around 1.5 to 2 seconds on the first run.

[alex-popov-tech]

same for me

[sheluchin]

Yes, I also had a brand new install when I posted my above comment and it took about 2 seconds to run for me as well.

Mine is around 2 - 3 seconds, plus the command J doesn't work at first. I need to toggle the tree off and on again to get the J works. Anw, great works, I believe this project will completely replace NERDTree some day.

[ms-jpq]

@finnng plus the command J doesn't work at first

thanks, good catch, i will fix that on my next PR.

to everybody who commented:

can I get more information on your local python setup? I will try to figure out why it is slower for you

[finnng]

What kind of info do you need?

➜ python3 --version
Python 3.8.5

[ms-jpq]

humm, you know what I think I will implement a profiler first and then ask you to turn it on later.

Can I tag you in this later? Im gonna sleep first, havnt closed my eyes in forever.

Thanks ^_^

[finnng]

Sure, I will help.

[ms-jpq]

Alright, so if you want to help out please do the following:

1. Update CHADTree to latest version.
2. Set let g:chadtree_settings = {'profiling': v:true}
3. Do :CHADopen
4. Do :messages

You should see something like this:

please post the results.

Mine takes 550ms to open on my laptop

thanks !

If you are on Linux, it should be notably faster with the same hardware, due to superior IO performance.

If you are not MacOS, you might get much faster performance if you shutoff your internet...

Apple in their infinite wisdom decided to block all executable from launching unless they pass an online security check

If you are on Windows, and it's slow I can probably do very little to help because I don't actually have a windows machine, I just test on my parent's TV box to make sure it runs...

Please also provide your computer's hard drive info if you are willing. ie. if CHADTree is installed on SSD or HDD

wtf 40 seconds to start?

and you have a NVMe SSD too!

ill investigate if pyenv is causing issues for people.

It takes like 0.5 seconds to start on my old desktop, under linux

[sheluchin]

Let me know if there's anything else I can do to help you track it down.
