Reading large table is slow

Hi,
              I have a table that has 80,000 records i have to read all data and I cannot filter records. It takes over 90 seconds. This is way too slow. I tried with setFetchSize of 50,100,1000,10000. Nothing helped.
     Connection conn = getJdbcTemplate().getDataSource().getConnection();

    conn.setAutoCommit(false);

    PreparedStatement stmt = conn.prepareStatement(sqlGetAllData);//, ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);

    stmt.setFetchSize(50);

What is the best way to retrieve large tables within 15-30 seconds.

Thanks,

Bharani
