The startup takes a long time

[Liferme]

Describe the bug
When starting up the APP, it frozes with the splash screen and a running icon beind, it always takes 10mins or more to get fully loaded.

To Reproduce
Steps to reproduce the behavior:

1. Go to Applications
2. Click on 'Arduino IDE'
3. See error

Expected behavior
Only few seconds to get load up.

Screenshots

Desktop (please complete the following information):

• OS: MacOS Big Sur (11.3)
• Version: Arduino IDE 2.0.0 beta7

What's the error if you start the IDE from the terminal? To start the IDE from a terminal, do the followings:

• Open Terminal.app and
• Run /Applications/Arduino\ IDE.app/Contents/MacOS/Arduino\ IDE.

What's the error if you start the IDE from the terminal? To start the IDE from a terminal, do the followings:

• Open Terminal.app and
• Run /Applications/Arduino\ IDE.app/Contents/MacOS/Arduino\ IDE.

The error still exists, it still takes moren than 5mins to load up.

[kittaakos]

What do you see in the terminal? Can you share the output?

[esp32croft]

Hi kittaakos,
I'm also using a Mac running Big Sur. However I don't get a 5-10 minute delay. More like abut 1 minute (subjective, could well be less).
I've attached my terminal log FYI, I don't know if you have many Mac users in your development/test teams.
StartupLog.txt

I've also included a log from my 10 year old MacBook running MacOs Sierra which also does not take 10 minutes.
MacBook startupLog.txt

Both show comments about certain processes being slow, and other warnings.
Hope that helps.

maybe related to #351 / #381?

Hello all.

I also have the same issue.
On Windows Version 21H1 (Build 19043.110) the startup dosent finish, the spalsh screen stays forever. Some entries from the menu bar are working for example "Help -> About Arduino IDE", but not all like "File -> New" dosent work.

Looks like it spends a lot of time checking for library and board updates... and retrying in case of error. Seems like these checks need to be more asychnronous.

"root ERROR Error while updating index in attempt 9."

These library checks can be done, and the results of those findings can be stored in json-files, a light database and loaded next time from there if after a quick check it is clear that there has been a change in the libraries. Personally I have been loosing the time of a good holiday waiting for the Arduino IDE coming up in previous version, staring at the screen as if tomorrow does not exist, wondering who in earth makes this to be so slow and is able not to itch its brain to rethink the necessity of all the initialisation checks, and if maybe the outcome of these checks is 99% the same as in other starting up of the IDE. Ideas like caching of results come to mind, databases as stated, or simply an option in the menu for the user to update the Library-Database. It is all a bit like a car starting by itself when you walk to the grocery-store, since maybe you want to use the car for that and then the car needs to be up and running. This costs all wasteful gasoline, or wasteful CPU, HD-time and what not.
Long story short: Needs heavely improved. Also in 1.8.x

I'm seeing the same problems. It appears that the IDE is looking to bind to port 50051 and failing repeatedly on startup (when launched from command line with /Applications/Arduino\ IDE.app/Contents/MacOS/Arduino\ IDE):

daemon INFO Restarting daemon in 5 seconds...
daemon INFO Failed to listen on TCP port: 50051. Address already in use.

Doing some sleuthing, it looks like at least the multipass (Ubuntu virtual environment from Canonical) daemon starts uses launchd to bind to this port:

$ find ~/Library/LaunchAgents /Library/LaunchAgents /Library/LaunchDaemons /System/Library/LaunchAgents /System/Library/LaunchDaemons -name "*.plist" -exec grep -H 50051 "{}" ; 2>/dev/null
/Library/LaunchDaemons/com.canonical.multipassd.plist: 50051

Unfortunately, just stopping the multipass daemon (using the Multipass's menubar widget) doesn't make the issue go away (since this is auto-launchd by launchd in the Mac and launchd appears to bind on port 50051).

I don't know what the solution here, and I'm not even 100% this is causing the launch times to be so slow, but hopefully this helps a bit.

[per1234]

Hi @gwachob. The situation with the gRPC port collision is discussed here:
#201

I don't know what the solution here,

The real solutions are discussed at #201 and arduino/arduino-cli#1260, but I'll provide instructions you can follow to resolve the port conflict:

1. Open this file in a text editor:

   ~/.arduinoIDE/arduino-cli.yaml
   

2. Change the port number in the daemon.port key to some port that is not already in use (e.g., "50052").
3. Save the file.

Now try starting the Arduino IDE again as before. It should now start up and work as expected.

the Arduino 2.0 ide startup needing 2 minutes, I start it form terminal, my Laptop is MacBook Pro (Apple Silicon) macOS 11.6.2 BigSur
I found it spend a lot time to update index ,following is the log

@rsora @Liferme @per1234 @cmaglie can this be prioritized? It's really painful having to wait 30 seconds for the IDE to check for library updates every time I start. I wouldn't mind waiting for updates to load when I specifically poll for it, but not when I just want to start editing code...

[FarhanKhosravi]

SOMEONE HELP US!!...
It's impossible to use an IDE with such SLOW opening...
i gave up using ide v2.0 and preferred to use old ide.. just because of this slowness

please fix this!!! it's very more important than your weekly cheap updates...... uh

startup time 7 min. rc-5

Please try with the nightly. This issue was a duplicate of #876 and was resolved with #1018.

Please comment on this; if the issue is still present, I am happy to reopen or open a follow-up. Thanks!

I am using the latest nightly version on my MacBook 2020 (intel base model i5), and startup takes about a minute.

[kittaakos]

Thank you for reporting it @AlexW00. Maybe it's #1428. Can you please share the logs with us?

The easiest way to get the logs is by starting IDE2 from a terminal. If you open a Terminal on macOS and start the IDE2 with the following command, you will see the logs in a new Terminal window.

open /Applications/Arduino\ IDE.app/Contents/MacOS/Arduino\ IDE

In my macOS, IDE2 is installed to /Applications. The command 👆 might be different based on your IDE2 install location.

The log starts with something like this:

/Applications/Arduino\ IDE.app/Contents/MacOS/Arduino\ IDE ; exit;
a.kitta@Akoss-MacBook-Pro ~ % /Applications/Arduino\ IDE.app/Contents/MacOS/Arduino\ IDE ; exit;
Starting backend process. PID: 89429

[AlexW00]

Sorry, my bad. Looks like I did not install the new nightly version correctly, and I still opened the old build. The new nightly version starts in seconds. Thank you for the improvement!
