    Hopefully, you know relational theory and have 'normalized' the data.
    When a given table gets too big, a typical solution is to export portions into
    new tables with a 'fixed value' column, eg: year. If the size of the year-table(s)
    are still too large, the next solution is export into second database.

    DBMS startups can be costly -- the indices get read and memory structure are build.
    Primary index will have only one entry per row of the table (by definition).
    Your secondary indices can have many entries per table row.

    Consider DROPing all secondary indices (they can be rebuilt later) and restart the system.
    If this has a major improvement, then you know that you should consider
    which indices you actually need and rebuild each and restart to see the
    impact. When it become 'too costly', the last index is your problem --
    consider why you have it and how you use it.
