- [Instructor] It pays off to optimize your file systems for your workload. There is not one general optimization setting that fits all environments. For instance, if our server was storing a lot of small files that need quick access we will optimize differently than if we were storing large movies that need to be streamed. These are two very different workloads. Some optimizations have to be done when the file system is formatted. Others can be done to a file system that already exists and many are done when the file system is mounted. File system geometry has to do with creating a file system that matches up with the RAID system under it. To specify file system geometry use the dash capital E option of MKFS while setting stride and stripe width. We can speed up access to the file system journal by making it larger or by creating an external journal and placing it on a faster drive. A larger journal uses more memory but reduces the frequency of write operations. Some general file…
