======= ext4 I/O performance parameters in / partition =======

For best performance in SSD units these parameters must replace the defaults in ''/etc/fstab''

  defaults,noiversion,auto_da_alloc,acl,user_xattr,noatime,errors=remount-ro,commit=20,inode_readahead_blks=64,delalloc
  
All in one line

I usually don't include ''acl,user_xattr'' in my desktop machines, but for multiuser machines (servers), it could be useful if you really want to use these settings

Apply changes by remounting:

  mount -o remount /
