I'd like to send a small update on my progress on the Performance Tracker project.

I now have a small setup of a server and a slave chugging along, currently collecting data. I'm following CURRENT and collecting results from super-smack and unixbench.

The project still needs some work, but there's a temporary web interface to the data here: http://littlebit.dk:5000/plot/. Apart from the plotting it's possible to compare two dates and see the files that have changed. Error bars are 3*standard deviation, for the points with multiple measurements.

Of interest is e.g. super-smack (select-key, 1 client) right when the GENERIC kernel was moved from the 4BSD to ULE scheduler on Oct. 19. Unixbench (arithmetic test, float) also has a significant jump on Oct. 3.

There setup of the slave is documented roughly on the page but I'll be writing a full report and documentation over the next month.

Comments are very welcome but please followup on performance@.

This looks really exciting!

Do you plan to add a way so that people can submit performance data? I.e., if I set up my own test box and want to submit a result once a week for that, will there be a way for me to get set up with a username/password, submit configuration information, and then automatically submit test result datapoints? Especially if I can specify both the X and Y coordinates so that I can backdate results should I go back and generate test results for old kernels?

Very neat, and I look forward to seein gmore!
