I honestly don’t know what’s going on there. The sole mod and contributor of the community keeps posting low quality shit purely to bash on Linux and people kept calling him out in the posts and getting banned from the comm for that.
Now I noticed the same mod has just locked comments on all posts to prevent having to ban anyone commenting on their memes
That’s not true. Yes there’s differences in how FS’ handle files. ext4 doesn’t need regular defragging because it self-defragging as part of its normal operation. Yes there may be cases where one needs to do a manual defrag on an almost completely full ext4 fs, but those would be extraordinarily rare.
