Performance Observations

Two versions of the QLANADMIN script were created: one using Perl and one using REXX[19]. The test runs obtained and displayed the same LDAP data, and were run on the LDAP server in test environment #2 but used the production environment LDAP server for data lookups. ``u'' and ``s'' refer to user and system CPU usages, in seconds.
