Manjaro KDE se fige pendant la copie de fichiers sur clé usb

Bonjour, j’ai remarqué que mon système se fige pendant certaines tâches comme la copie de fichiers ou quand je télécharge des fichiers torrents. Et pire encore, je dois attendre que firefox finisse sa “danse” avant d’accéder à un nouvel onglet tellement ça rame. Pourtant ma configuration n’est pas si mauvaise que ça: intel celeron n2840 hd graphics. Je suis sous kde avec le kernel 5.4 lts btrfs.
Si quelqu’un a ou a eu les même problèmes, ou si connait la solution —prière de m’aider !

Hello, combien as-tu de RAM ?

j’ai 4 giga de ram

Je ne suis pas familier avec BTRFS.
J’aurais tendance à conseiller de tester le plus récent Kernel LTS, le 5.10, pour voir si les performances s’améliorent ou non.

Il faudra attendre d’autres suggestions.

Ok merci
