Thanks for reporting, philor. I check these over carefully. Bogomips and other performance metrics look normal in this job. For a few days, including 2017-03-15, additional "gray marking checks" were slowing down Android Debug mochitests significantly. M48 was running close to 90 minutes during this period. I think this one took just a little longer. Those checks have been disabled on Android now. Most Android Debug mochitest jobs run in 30 to 45 minutes currently; M48 is one of the longest running, typically 80 minutes currently.
