Not too often that a company goes back to a previous vendor after switching, but Hydro Mississauga Ltd of the eponymous Ontario town, is returning to the Hewlett-Packard Co HP 3000 with Mitchell Humphrey & Co financials, after three years of using an IBM Corp 4381: the change is being made in an effort to save $2m in operating costs and gain performance improvements, dumping the 4381 for an HP 3000 Series 957 running HP MPE/iX; it says the power of the new machine has enabled it to reduce its operations shifts from three to two and to cut overnight batch processing from 11 to four hours, and one table-loading job was shortened from 14 hours to 20 minutes – and on-line response time is significantly improved; it switched from an HP 3000 Series 70 that lacked the capacity needed in 1989, moving to the 4381 with Dun & Bradstreet Corp software.
