Once one starts using statistical performance tools, and wondering what all these numbers mean, one should at least go take a look at Drongowski's "Basic Performance Measurements for AMD ... Processors" http://developer.amd.com/Assets/intro_to_ca_v3_final.pdf which gives a great synopsis of what meaning numbers are. Then it's worth it to check out CodeAnalyst which runs on top of OProfile. Cheers -- Quentin Hi Mr. Brandy,

Thanks for the post.

Some notes about oprofile under Ubuntu 10.04 and the uncompressed kernel image. Currently the .deb packages containing the uncompressed kernel image can be found at http://ddebs.ubuntu.com/pool/main/l/linux/. The package names no longer follow the naming convention linux-image-debug-{version}.deb. Now, if, for instance, your linux version is 2.6.32-31, then you should download and install a package like linux-image-2.6.32-31-generic-dbgsym_2.6.32-31.61_i386.ddeb (for and x86 architecture). More information about this new naming convention at can be found at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/289087/comments/34 Thanks for this post, it has been very useful for me.

Or did that come out in a later version of OProfile? You’ve forgotten to explain about the “ophelp” command, which can be very useful for finding the esoteric event descriptors.
