Hi Jon I did some investigation. There's some sort of Intel thing that can be switched off at the risk of overheating the processor. Past that I don't know what to do in Linux to speed things up. Given the speed of the processor and dual cores I'm amazed at how slow PCs are compared to an 8 bit PIC running 40Mhz. John
