Yes, something relatively simple should do. For a process writing to syslog, you get a system call, two context switches and a number of other things, as compared to simply writing a few bytes in memory. And you should probably not try to benchmark printk by recording all system calls using it, your kernel will burst. _______________________________________________ lttng-dev mailing list [email protected] http://lists.lttng.org/cgi-bin/mailman/listinfo/lttng-dev
