    Time keeping

    Keeping accurate time is essential to a properly-functioning database. Ensure that you follow the guidelines for synchronizing each Couchbase node using Network Time Protocol (NTP).

    Clock Sync with NTP

    Disable Transparent Huge Pages

    You must disable the THP memory management system on each node that runs Couchbase Server.

    Disabling Transparent Huge Pages (THP)

    Set kernel swappiness

    The kernel swappiness setting defines how aggressively the kernel will swap memory pages versus dropping pages from the page cache. You need to set the swappiness setting to 0, or at most 1, for optimal Couchbase Server operation.

    Clusters with less than three nodes

    Couchbase Server clusters with less than three nodes are not recommended in production. However, you might find a need to have a smaller deployment for test and development purposes.
