Hi, I have reinstalled system and choose btrfs as system default filesystem. System is overally very slow, maybe this can be also caused by systemd(I had installed archlinux without systemd before), but dont think so.
It takes about 30s to start any application, openning webpages is slow, downloading....copying between folders is about 5MB/s.
Can be this caused by btrfs?
I have noteebook ibm x41, with 1,5ghz cpu, 1,5gb ram.
Is possible and how to backup data on system disk with btrfs and change filesystem to ext4?
