summary:

  • xfs: excellent performance large files. low speed small files. choice /home. -reiserfs: excellent performance small files. choice /var.
  • ext3: average performance, reliable.
  • ext4: great overall performance, reliable,has performance issues sqlite , other databases.
  • jfs: overall performance, low cpu usage, extremely fast resume after power failure.
  • btrfs: best overall performance (with compression) , lots of features. still in heavy development , supported, considered unstable. not use filesystem yet unless know doing , prepared potential data loss.
