What options can I tweak to make Juno feel less lethargic?

xiaodai · October 19, 2019, 12:54pm

I open up Juno and I try using CSV and it feels like 30s has passed before it can register the action. Normally, in Julia REPL it only takes about 3s.

What options can I choose to helpo with this? I tried cycler, it didn’t help.

Switch to Sublime Text 3 Here is the startup, and here is the execution of some code.

But seriously: I think pre-compilation is hidden in that observed delay.

It’s weird the same task only takes 3 seconds and in juno takes 10, sometimes 30

You are right, something is going on.
Atom.

ST3

Saw the guide here. IT’s way too complicated and involves so many steps. Definitely a barrier to entry.

# How to use Julia with Sublime Text 3

## Rationale

This document was written as a personal aide-memoire, which means it will be mostly limited to the ways in which I myself use the editor. Hence the discussion is limited to the programming of Julia and writing of markdown files. I do hope that other people may find it useful too, however.

## Installation

### Sublime Text 3

Download the editor from the website [https://www.sublimetext.com/](https://www.sublimetext.com/). (Isn't it nice that the download is only 8.8 MB?)
As I am on Windows 10, I will describe the installation and use of the editor on that platform. I do have the Windows Subsystem for Linux installed
and I use it regularly, so I will describe use of Julia running in an Ubuntu Linux from within the editor running on Windows.

### Install Package Control

The first thing you would want to do is install the package **Package Control**.
Use the menu item **Tools/Command Palette** (key binding: `ctrl+shift+P`), type `install`, and an item **Install Package Control** will bubble up. Select it, and practically instantaneously you will get a confirmation box that the package was installed.

By the way, remember the key binding `ctrl+shift+P`: it will bring up the **Command Palette**, and practically everything that you might need can be done from here.

I have a Sublime License for many years… just waiting for a julia package that ties all of these together.

BTW, vscode is failing as well on v1.3

This happened about one year ago. Thought it was partially fixed

PetrKryslUCSD · October 20, 2019, 7:50am

Sorry, I don’t follow. This is in reference to what?

The issue with juno slow downs

PetrKryslUCSD · October 20, 2019, 8:45am

I don’t remember that. Perhaps @pfitzseb would know what is going on?

xiaodai · October 20, 2019, 8:52am

See my post Why does Juno make my code run slower than in VScode?

I can’t repro this:

Did you make sure that Juno and the REPL are running the exact same versions of Julia, CSV.jl, and all dependencies?

There is also some work happening (asynchronously) when starting a new process (and at some other points as well, e.g. when compiling the code for generating the outline or completions and so on), so maybe that factors in here?

On Julia 1.3rc4. Switching back to Julia 1.2 solves the issue. So the issue for me is with Julia 1.3-rc4. The problem is also not there with Julia 1.3-rc3, so seems to be an issue with rc4.
