Problem Description

I just installed Flow Launcher onto my laptop running Windows 11, and it is using around 600MB of memory, whereas on my desktop (Windows 10) it only uses about 20MB. What could be the cause of this high memory usage?

To Reproduce

Install Flow Launcher v1.19.0
Observe high memory usage

Is the one installed on your Win 10 also v1.19.0?

Memory usage tends to be high during usage when searching for files and browsing the plugin store, but tends to drop down after a while on idle. Does the memory usage drop on win 11?

600mb is still quite unusually excessive, were you searching for files that return a large amount of results? Does it happen again after a restart of flow?

supercam19 commented 2 months ago

My Windows 10 machine was running v1.18.0, so I updated it but am still getting normal memory usage amounts.

After a bit of testing on the Windows 11 machine, I found that Flow Launcher would use about 350MB when I started it. Opening the settings would make it rise to ~600mb and scrolling through the plugin store to ~1gb. Even after idling for a while, the memory usage wouldn't drop.

This persists after restarting Flow and the laptop.

xsidexpt commented 1 month ago

Just o add a little to this issue, I have seen very high ram usage that gets cleared when I restart the app. Freshly open it seats at around 150mb which is fine, but I have seen 1.5Gb for no apparent reason. This of course is not ideal, even in systems like mine with enough ram for this to mostly under the radar. I am using Windows 11 and the latest available version of flow launcher 1.19.2

xsidexpt commented 1 month ago

I have been able to pinpoint my high ram usage to copying images whilst having Clipboard+ or ClipboardR plugins

jjw24 commented 3 weeks ago

@supercam19 are you also using the Clipboard+ or ClipboardR and getting high memory on copying images?

xsidexpt commented 3 weeks ago

I was Yes! I reported the issue to the Clipboard + dev, and it is currently patched in the release version. You still should expect an increase of ram when you have an image in your clipboard, but nowhere near as bad as it was before.
