Thanks for the Ogg Vorbis audio- I listened to the whole thing, and it was quite good.
Thanks for the slides as well.
I have seen that you have contacted developers in the case of regressions, and that is a key point. Always report bugs, as otherwise developers don't know they are there. They don't read every site.

However, I am afraid many bug reports stop somewhere in along the line.
Also, with several distro trees nested inside each other some patches may have been solved only in one branch/fork; think of the sequence Debian>Ubuntu>Mint. What happens with a bug report to Ubuntu, will it reach Debian and/or Mint? We can only hope that all distros will further bug reports to the actual source and not make a fix peculiar to their domain.
Thanks for your pdf and ogg!
NP - If there are any other topics of interest, I am more than happy to submit a paper to conferences when there is community interest.

In the end, cooler heads prevailed and a KVM patch was applied to alleviate the situation, but the effort to get bugs filed and communicate with the teams was quite frankly a waste of time and effort. The numbers stood, the benchark stood, and a fix was made. Cost to me was about 30 or so emails, personal attacks and days of wasted effort lodging bugs and arguing details that were consequently closed by holier-than-thou developers. I did try both ways in this case - I asked politely on mailing lists, I raised bugs as requested.
The reality of the situation is that if the affected parties aren't willing to get to the analysis stage, then there is virtually no point in filing a bug without a receptive developer.
As I mentioned in the talk, there is no reason that a lot of this should be surprising to developer of a project. The tests Phoronix uses are consistent, the tests are trivial to run, but the results are rejected by the affected projects far too often. Often it takes a slashdot response to get peoples attention.
Does the same sort of thing happen when Windows benchmarks like 3DMark or other suites are run?
Are you kidding me? You should be read some comments after some site posts benchmarks where one video card or CPU performs consistently better than another. A lot of the article writers know that a flame war is going to happen so they will end the article with something like, "let the flame wars begin." It always amazes me how emotional people get about flaws being found in something. They always take it as a personal attack. That attitude probably comes about from the trolls who do try to use flaws and regressions as personal attacks. That's a whole other problem.

I like those companies beause of their history and I tend to like their styling better, but every model made by every manufacturer has some flaws and every manufacturer has some model that has more than an acceptible number of flaws. They are all mechanical and made by humans, they ALL break. My favorite argument to listen to was how much better Toyotas were than all other manufacturers. I like Toyota, but I could, at that time, list off 10 - 15 major flaws found in various models. People just need to learn to accept the fact that everything has flaws, man made or not, but especially man made items. There is no such thing as the perfect OS, software, car, coffee maker, whatever. The important thing is that when flaws or regressions are found is that someone takes a serious look at it, tries to reproduce it, if it's reproducible then fix it. Why does that have to involve personal attacks?
