With such number you should keep in mind that, Larger data will require more memory and can impact overall system performance.

You may consider increase the HASHEXP value to maximize the efficiency of the hash object lookup. Read more here DECLARE Statement, Hash and Hash Iterator Objects . So increase it and see if you reach better performance.
