Hello all, I am running oprofile on some program. Following is the oprofile output.
----------------------------------------------------------------------- Counted GLOBAL_POWER_EVENTS events (time during which processor is not stopped) with a unit mask of 0x01 (mandatory) count 100000 samples % app name symbol name 985913 8.6083 vmlinux mark_offset_tsc 584473 5.1032 libc-2.3.2.so getc 295901 2.5836 vmlinux ide_outb 270823 2.3646 vmlinux _spin_lock 249791 2.1810 vmlinux _spin_unlock 236140 2.0618 vmlinux timer_interrupt 175249 1.5302 ld-2.3.2.so do_lookup_versioned 140429 1.2261 sendmail putc 138739 1.2114 sendmail stabhash 134145 1.1713 sendmail getc ----------------------------------------------------------------------- >From this output what I can analyse is that mark_offset_tsc(which is called from do_gettimeofday), and some other timer functions, are taking most of the CPU. Is there any faster implementation of do_gettimeofday. I am using kernel 2.6.10. with dual P4. What I found from google search is: http://lwn.net/Articles/9266/ , which is only for kernel 2.4 Thanks for help. -Puneet - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
