Why would sysfs write be slower than ioctl?Sysfs is generally one-value, one-file. open, read/write, close. ioctl() OTOH does everything (e.g. a whole key table) in one syscall.
There are binary sysfs attributes. For ioctl you also need to open and close the device. Plus, how often do you expect to perform this operation? Don't you think you are trying to optimize something that does not have any real performavnce impact here? -- Dmitry
