Early on he describes the use of the real time clock to generate an interrupt 100 times a second. He explains that this value was chosen early in the development cycle of the linux kernel and is therefore relatively low compared to what current hardware can make good use of. He mentions that the alpha port of linux uses a 1024Hz interrupt rate and that patches have been made for the Intel kernel to give it the same rate while maintaining the interrupt rate that appears to userland programs such as top at 100Hz. I'm just wondering what the benefits of increasing this value are and whether these patches are going to be included in 2.4?
