Bonjour,
Je parlais de cet espace de stockage, j'ai eu l'impression qu'en le vidant cela avait amélioré les performances, cela est-il lié ?

Hey, @Dreamtim_photos. Thanks for the screenshots & we're sorry for the delay in getting back to you.
The screenshot shows the cloud storage quota in your subscription. It does not affect the Lightroom's performance on your device.
In Lightroom's context, upon 100% usage, sync will pause and any new imports and edits will remain stored locally and won't be backed up on the cloud.
You can learn more about what services use the cloud storage in your account: https://adobe.ly/40HIOo1;
I hope this helps. Thanks!
