Takes x 6 times to load in compare to the old IDE

[zaid894]

Describe the bug
Takes so much time to launch and load sketches that you allmostly forget what have you been waiting for, the load time is really too long in compare to the old IDE.

I have an M.2 and 2 x 4GB 3200 MHz RAM though it takes the 2.0 IDE around 31 Seconds to start and load a sketch while 4.5 Seconds at version 1.8.

To Reproduce
Steps to reproduce the behavior:

1. Run a sketch
2. Use a stop watch.

Expected behavior
I was expecting for much better launch time.

Desktop (please complete the following information):

• Windows 11
• 2.0.0-rc3

@zaid894
We are aware of the startup-time issue, but in order to better investigate can you give us more info?

• number of installed libraries (you can count the folders in the Sketchbook's libraries folder)
• number of platforms installed and which ones
  example:
• AVR
• SAMD
• MBED
• ESP32
• ESP8266
• STM32Duino

Thank you :)

In my current installation, I have 47 libraries (I used to have over 280) and 21 platforms. I just restarted the IDE and it took 19 seconds from typing arduino-ide in a terminal until my sketch was open.

I see lots of stuff like this in the output: the IDE making a bunch of connections to check for updates before loading the editor. These checks should be deferred and run in the background.

[ubidefeo]

thank you @ckuethe for the comprehensive output.
we'll look into why all those signature errors show up

u.

[ckuethe]

I don't think the signature errors are as important as not blocking app startup while checking for updates. When I turn off my network the IDE loads much more quickly: root INFO Finished loading frontend application after 5.734 seconds

[ckuethe]

Wow. rc5 is even worse.

as not blocking app startup while checking for updates

The IDE starts to await for the index-update in this commit: 9aff90b#diff-f463d1c276a9080ec522ead62c6dd596e5bf330b093b7d51b71738c9795d0fdaL60-R60.

Auto index-update CLI changes:

• Core and lib search command now update indexes first arduino-cli#1043
• Fix update indexes running when not necessary arduino-cli#1063
• Change core search to update indexes only after 24h from last edit arduino-cli#1237 (👈 this could be interesting)

I did some measurements on the HEAD (using console.time):

(Note: the numbers do not necessarily add up, but all >= the sum of the sub-tasks.)

On my dev env, zero cores and libs are installed. Still, the core index update takes a long time and heavily depends on the 3rd party URLs config.

It can take 60s+ to load on my laptop, and seems to take at least 30s before there's any visual indication that it's loading. Admittedly I have an HDD and not an SSD, but something like Visual Code doesn't have this problem. I'm on Windows 10 - is there a way to show startup logs?

[per1234]

is there a way to show startup logs?

Hi @stodge. You should get everything of interest by starting the Arduino IDE from the command line.

I'll provide instructions for how you can do that and then share the output here:

1. Start File Explorer (AKA "Windows Explorer").
2. Open the Arduino IDE installation folder
   (usually C:\Program Files\Arduino IDE or C:\Users\<user name>\AppData\Local\Programs\Arduino IDE).
3. In the folder listing of the Arduino IDE installation folder, hold the Shift key while clicking the right hand button on the mouse.
4. From the context menu, click "Open PowerShell window here".
   PowerShell will now open with the current directory set to the Arduino IDE installation folder.
5. Type & ".\Arduino IDE".
6. Press the Enter key.
   Debug output should now be printed to the PowerShell window as the Arduino IDE starts (or fails to start).
7. Wait for the Arduino IDE to finish starting, or failing to start.
8. Switch back to the PowerShell window if the Arduino IDE window took the focus.
9. Right click on the title bar of the PowerShell window.
   This will open a context menu.
10. Select Edit > Select All from the context menu.
    This will select all the text in the PowerShell window.
11. Press Ctrl+C.
    This will copy the contents of the PowerShell window to the clipboard.
12. Paste (Ctrl+V) the output in a reply to this GitHub issue thread.

Please let me know if you have any questions or problems while following those instructions.

[stodge]

Thanks. I ran the command as you suggested, and it did nothing for 5 minutes until I pressed RETURN in Power Shell. It still has the problem where you the splash logo sits over everything on the screen and you can't bring any other window on top of it. Will post the logs in a bit.

I started the IDE from the command line before you replied, but as a foreground process. Again, it didn't do anything for 5+{ minutes until I pressed return in PowerShell and both instances started at the same time.

I'll close both instances and restart. More later... Thanks.
