As seen in http://graphs.mozilla.org/graph.html#tests=[[29,63,22]]&sel=none&displayrange=7&datatype=running there are two lines where there should really be one.

Looks like there's only one data series; are you sure there isn't some kind of bimodal distribution going on in the performance results? 

I know people have seen this kind of thing on other tests.

Yeah, that appears to be bimodality.

I was comparing to linux and windows for the same test http://graphs.mozilla.org/graph.html#tests=[[29,63,18],[29,63,8],[29,63,22]]&sel=1338802936533,1338845254901&displayrange=7&datatype=running

It seems there are two data points for each changeset for osx which seems wrong?

Ah, that is odd - thanks for pointing that out.

I haven't seen this problem before, it could be from duplicate reporting on the Talos side.. I'll check the server logs.

graphserver has been replaced by perfherder.
