Release 2.0.0 beta 4 very slow

[rei-vilo]

The release 2.0.0 beta 4 is very slow compared to previous releases and other similar IDEs.

• At launch
• During normal operation

hi @rei-vilo could you tell us something about your operating system and configuration ? are you comparing to beta3 and you saw beta3 was faster ? thanks!

[rei-vilo]

Sure, I'm using Debian with Gnome on a i5-8259U with 8GB of RAM.

Beta 4 is slower than beta 3, and Beta 4 is much slower than Visual Studio Code running on the very same configuration, albeit both Eclipse Theia and Visual Studio Code are built on the same underlying technologies.

Slow speed refers to calling menus, going from one pane to another, opening a window, and alike.

@rei-vilo
would you be able to specify what is slow?
there aren't significant changes between Beta 3 and 4 which should make it sluggish.
Are you experiencing UI slowness?
Which parts seem to be slower in 4 than 3?

thank you
u.

Some unscientific measures of how long it takes to launch the IDE:

• Arduino IDE 2.0.0 beta 4: 34 s on first launch then 13 s on subsequent launches
• Visual Studio Code 1.54.3 with Arduino extension 0.4.0: 8 s on first launch then 3 s on subsequent launches

@rei-vilo
They are 2 different products, also the Arduino extension for VS code does a lot of things, but it's not based on our CLI.
The IDE is a front-end to a CLI backend, and it might take some time to get all the pieces working.
You cannot expect them to work the same.

The difference in speed between 3 and 4 is something I'm curious about, though

Seems to be also reported at #385
