One of my goals is to review all the talos tests for accuracy and usefulness. 
It came to my attention earlier this summer that the dirty tests 
(tspaint_places_generated_med, tspaint_places_generated_max) are outdated and 
providing little to no value.

After investigating these tests in more details it became obvious that we were 
running 8 jobs/push at 15 minutes/job and ending up with the same numbers as 
ts_paint.  Looking at the profile in detail, we have somewhat realistic data in 
the profile:
https://wiki.mozilla.org/Buildbot/Talos/Tests#ts_places_generated_med

The problem is no elements in the UI are accessing it.  I thought a simple 
profile update would help, but our Firefox engineers have optimized the startup 
path so much that we would need to do more than a startup test to make this 
useful.  

In bug 771142 (https://bugzilla.mozilla.org/show_bug.cgi?id=771142), there is 
discussion about what we could do and what value this brings.  After looking 
into this and asking interested parties, I am proposing to turn off these tests 
next week.

Please comment in the bug or on this thread if you feel these tests should 
continue as startup tests.
