I get *70,093* dhrystones/second on my 33 MHz 88100 (Motorola model 8612) with the Diab Data dcc88 (ver. 2.34) compiler. I get around 42k dhrystones/sec with my 20 MHz 88100 machine. And this is dhrystone 2.1. The Solbourne compiler must be broken! -- Motorola Semiconductor Inc. Hunter Scales Austin, Texas {harvard,utah-cs,gatech}!cs.utexas.edu!oakhill!hunter #include
