"Show applications" is slow on an AMD A8-7410

[widon1104]

I use ubuntu19.04, "show applications" take about 2 ~ 3seconds to get result in my computer.
I think it is too slow, I don't know whether there is a way to make it faster, "show applications" is very frequent action.

I install deppin15.10 in my virtualbox, assin 2GB mem and 1 cpu core.Deepin has almost the same feature , but deepin only take 0.5 seconds to get result.

Thank you for your bug report. What do you call "show application"? How do you trigger it?

[Daniel van Vugt (vanvugt)]

This bug report came from elsewhere. It's about the icon spring animation.

But the animation varies depending on how you initiate it. For example, Super+A is faster.

Also, please try uninstalling your extensions:

'full_clock@soulsuke'
'<email address hidden>'
'<email address hidden>'
'<email address hidden>'

and then confirm for us if the bug still occurs?

[widon1104 (widon1104)]

This problem still occurs.
The deepin launcher is written by c++, the gnome launcher is written by js,
c++ is much faster (at least 5 times) than js I think.

I hope gnome do not use js, use c or c++ to Performance sensitive feature.

The deepin launcher code:

Please also:

1. Remember to reboot the machine after uninstalling all extensions and retest.

2. Tell us how you are launching "Show Applications"? Is it via a mouse click, or keyboard?

3. Are you using the Ubuntu Dock in Gnome Shell or the traditional Gnome Shell dock?

[widon1104 (widon1104)]

I use mouse click and Ubuntu dock.

Even in VM, the deepin launcher is much faster than gnome launcher, because deepin launcher is written by c++.

[Daniel van Vugt (vanvugt)]

Yes we know and expect other desktop environments will be faster than Gnome at some things.

[Sebastien Bacher (seb128)]

Well, it's still unclear what you call "show applications" and how you trigger it. Can you make a screencast of the issue?

[widon1104 (widon1104)]

look at the Lower left quarter，use mouse to click that button.

[widon1104 (widon1104)]

mac has the same feature, and it's very fast,
mac should not write this feature use slow script language like JS.
