We need to port existing linux unserlevel soft from i386 to ARM. Our tasks are lot of string searchign like lot of strstr(). I need to understand performance ratio factor for such tasks between ARM 266 MHz and Intel 800 MHz(via), very roughly. I don't have access to the target ARM box so I cannot make direct experiments and measurements. How can I roughly and theoretically come up with some factor ? Please help me. Yakov
