I've just started playing with this thanks to Alan, so bare with me.
It seems that the hangup is on the appside in libcrutil, 87% of the time
spent there. Does anyone know how I can get the function breakdown from
within the libs? optstack doesn't seem to be doing the right thing for
me... I've also set the kernel image to the correct place, but I still
get a listing for no-vmlinux.
Running SDP

CPU: P4 / Xeon, speed 2399.55 MHz (estimated)
Counted GLOBAL_POWER_EVENTS events (time during which processor is not
stopped)
with a unit mask of 0x01 (count cycles when processor is active) count

Unless it's in a tight poll loop on a non-blocking ioctl or similar, the network suckage you're looking for is going to look just like an idle task as far as a profiler is concerned. What's the difference between your task (presumably) sitting waiting on a network event and an xterm sitting waiting for a keystroke? Keith |

Profiling can find your CPU bound bottlenecks but there's no easy way to account for any wait time. Maybe you should look at strace and write some scripts to process the output. You should be able to get a timestamped output of when you are making system calls. > What's the difference between your task (presumably) sitting waiting on a > network event and an xterm sitting waiting for a keystroke? > > Keith > > > > > ------------------------------------------------------- > This SF.Net email is sponsored by The 2004 JavaOne(SM) Conference > Learn from the experts at JavaOne(SM), Sun's Worldwide Java Developer > Conference, June 28 - July 1 at the Moscone Center in San Francisco, CA > REGISTER AND SAVE! http://java.sun.com/javaone/sf Priority Code NWMGYKND > _______________________________________________ > Chromium-dev mailing list > Chr...@li... > https://lists.sourceforge.net/lists/listinfo/chromium-dev -- Alan Matsuoka Global Professional Services Red Hat Canada, Ltd mailto:al...@re... |
