The first thing to test is whether it's Python or the database that's
the bottleneck. 1500 rows isn't all that much for a database, but it
might not be trivial either.

Even if the bottleneck is Python, the solution might be to limit the
amount of data that you process. For example, rather than displaying all
1500 records in a tree (nobody wants to scroll through 1500 records
anyway), try grouping them by the first letter of their name. Display a
tree consisting of each letter, then when the user clicks that letter:

  cur.execute("SELECT * FROM clients WHERE name LIKE '" + letter + "%'")
