[vtk-developers] New pipeline & performance

[Dean Inglis]

I have observed with two of the tests
I submitted, try to keep track of and threfore
maintain, a serious performance hit after
pipeline changes committed Monday October 11.
The time to execute TestSplineWidget and 
TestImageTracerWidget now run up to 5x slower.
Running the equivalent tcl scripts as they
appear in Examples/GUI/Tcl shows the same perf. hit
as reduced interactivity, presumably due to
vtkSplineWidget (try ProbeWithSplineWidget.tcl
and ImageTracerWidget.tcl).  

Questions:
1) is there currently (if not, could there be) a
way to track execution time histories for nightly
dashboards? 
2) how should performance issues be addressed?

In regard to 1), if the ongoing pipeline changes
manage eventually to rectify the problem, it would
be helpful to know when.
