Why is ZFS bad?

If you're looking for the absolute-fastest uncached and uncompressed performance, ZFS is unlikely to satisfy. While not much slower than alternatives like ext4 or xfs, it is generally at least a bit slower—again, if you design your benchmark workload to exclude the benefits of caching or compression.

Is ZFS better than XFS?

Architecture. While ZFS is designed to be reliable, XFS' main selling point is its support for fast parallel I/O. ... As mentioned earlier, XFS offers higher performance it terms of I/O. Being a Journaling File System it still keeps track of changes that are to be made to the data on the disk.

What is ZFS in Ubuntu?

Ubuntu server, and Linux servers in general compete with other Unixes and Microsoft Windows. ZFS is a killer-app for Solaris, as it allows straightforward administration of a pool of disks, while giving intelligent performance and data integrity. ... ZFS is 128-bit, meaning it is very scalable.
