I would agree that Teradata Stored Procedures are not inherently slow, and can add a lot of value. But what I have seen is a tendency for those
writing SPs to use CURSOR (serial row-at-a-time) processing and procedural logic. For large volumes of data, that does tend to be dramatically
slower than SQL "set processing" which can take advantage of the parallel nature of Teradata.
