    After VPS Migration, Disk Performance Has Become Slower


    Hello,

    Recently I migrated VPS from the old server to a new server. Unfortunately, after migration, I found that Disk performance has become slower on the New server.

    Has anyone else faced this problem after the migration of vps?

    Hello Clay,

    Please confirm if the server specs are similar or not to the old server.

      Hello Rachel,
      The new server has higher specs than the old server. In addition, the new server has the latest ext4 filesystem.

        After VPS Migration, Disk Performance Has Become Slower because the set of the filesystem features is not enabled during peak time. The below features commonly impact the extX filesystem.

        noatime

        This feature disables registering a file access time.

        data=writeback

        This feature allows metadata to be written asynchronously.

        barrier=0

        This feature enables/disables the use of write barriers in the journalling block device code. When turned off, it allows you to bypass strict orders while writing journal commits.



        The last element is enabled by default in ext4 and might be the reason for the visual performance degradation compared to the same device formatted with ext3.
