Subj:   Select * from mytable

MyTable has tens of millions of rows.

The astute user wants to look at the first 2000 rows so they enter:

lock MyTable for access
Select * from MyTable;

Explain says the query will use an all amps retrieve. Why do the nodes take over 2 minutes to start returning rows when there is no one on the system? Based on experience with other database systems I expect the system to start returning rows.
