There are several commands in linux to view the information of many
data in an I/O interrupt (depending on the specific hard disk).③D1: Turn on DMA mode.④X66: In a hard drive that supports udma-capable, this parameter can support data transfer mode for dual DMA channels.⑤u1:linux when dealing with disk outages, you can unmask other interrupts or respond to other interrupt-related tasks.To view the above changes, you can use the command: #/SBIN/HDPARM/DEV/HDATest disk I/O performance you can use the command: #/SBIN/HD

Abstract: In order to realize accurate timing of computer software, a high-precision microsecond-level timer is designed. The timer uses the high-precision counter of the computer to complete the timer function. The timer precision on the pentiurn 1 V computer on the Great Wall can reach dozens of microseconds. To test the performance of this high-precision timer, a control program based on Windows multithreading mechanism is developed using Visual C

But he believes that the development of Linux is due to the fact that he is able to keep the Minix small, so that students can learn in a semester, and therefore not accept the expansion of many people around the world to minix
