I guess it's the benchmark. In contrast to its FP counterpart, Dhrystone doesn't crunch numbers most of the time. It also performs lots of string operations, for example (memory access == slow). -- Michael "Tired" Riepe <[EMAIL PROTECTED]> X-Tired: Each morning I get up I die a little ------------------------------------------------------------------------- Take Surveys.
