Hi dudes, I have some questions about btrfs. 1) Lets say i did a basic command-line install of ubuntu on a BTRFS drive, how would i be able to enable compression on it? 2) If i enable compression, would it compress the files allready copied in the installation? 3) By enabling compression it would make loading off a usb much faster, but what about the "ssd" command? 4) If i enable "nobarrier" , to make the performance faster, is it even worth it? I got some info here: BTRFS Commands and here: BTRFS wiki Thanks dudes!
