Hi Jon, thanks for your article!
After moving an implementation of generating JSON output for ORDS from APEX_JSON to JSON_OBJECT_T, we saw that:
Out of interest, can you reproduce this behavior in your tests, or does adding "apex_util.prn ( l_json_clob, false );" take the same time, independent if the CLOB comes from JSON_OBJECT_T or APEX_JSON?
