Here is a list of regressions we have detected:
+--------------+---------------------+------------------+---------+
| keyrevision  | platform            | test             | percent |
+--------------+---------------------+------------------+---------+
| dd2018a5f894 | Ubuntu HW 12.04     | Kraken Benchmark | -3.65%  |
| dd2018a5f894 | Ubuntu HW 12.04 x64 | Kraken Benchmark | -3.63%  |
| dd2018a5f894 | WINNT 6.2 x64       | Kraken Benchmark | -3.73%  |
| dd2018a5f894 | MacOSX 10.6 (rev4)  | Kraken Benchmark | -5.53%  |
| dd2018a5f894 | MacOSX 10.8         | Kraken Benchmark | -4.69%  |
+--------------+---------------------+------------------+---------+

unfortunately, no improvements.  The good news is this is all on a single benchmark, the bad news is this is across all platforms.

according to an analysis of the datazilla data (looking at the subtests), we fail by a 43% regression on the 'audio-oscillator' subtest (raw test can be found here: http://hg.mozilla.org/build/talos/file/c36273c3498d/talos/page_load_test/kraken).

this bugs get the prize for the first firefox 34 talos regression to be filed :)

I backed out the patch from bug 1039965. Can this bug be closed?
