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 [EMAIL PROTECTED]
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!
