I am using DB2 9.5.5 and cannot migrate to 9.7 anytime soon, so I cannot use
Created Global Temporary Tables (CGTT).

I am wondering how Arrays are implemented for stored procedures and what the
performance is compared to declared global temporary tables (DGTT). In order
to improve performance, I want to use arrays instead of a DGTT, but I want
to make sure that Arrays are not creating a DGTT under the covers.

Assume that Arrays provides me with the functionality I need.
