Thanks for the deep dive, Elvis! :) Is it possible to adjust some of these settings in the Ubuntu packages, or is just the way it will be going forward? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to python2.7 in Ubuntu. htt

[Touch-packages] [Bug 1638695] [NEW] Python 2.7.12 performance regression
