 Hi,
 I was testing a normal pII450 against a pII450 xeon with 1024 kb cache.
 The application was Gaussian94 compiled with the f2c-gcc combination, the
 tests jobs were geom. optimizations and freq. calculations on 10-atom
 molecules with 70-250 basis functions and the results were disappointing:
 the xeon was only about 5 % faster, despite the bigger and faster cache.
