    Thanks  for  solution.  After REINDEX command for most significant
    tables,  perfomance  was  restored. I will do this procedure every
    two days.

    I  have only one small question. Can I do REINDEX during inserting
    of  information  into  tables. Or I must block somehow updating of
    tables.

Best regards,
