    How to detect energy and performance issues of your mobile applications before your users?

    In this article, we explain the issues of mobile applications energy and performance, and how to detect them before your users. Performance and energy, essential criteria for mobile applications The performance of a digital solution is an important criterion for user. Without performance, users will be critical and in the worst case will no longer use the service. This factor has been reinforced with mobility, given the less powerful platforms and networks with unequal characteristics.

  • Why is measuring performance with the CPU a mistake?

    Why is measuring performance with the CPU a mistake?

    In his Upscale 2018 presentation last march, Brendan Gregg, senior performance architect at Netflix, explains why the CPU isn’t a good metric for measuring performance. Everyone uses %CPU to measure performance, but everyone is wrong Brendan Gregg, senior performance architect at Netflix This is an opportunity for us to revisit what we have been pushing for a long time: How to measure performance and resource consumption reliably?

    How apps killed my phone battery?

    The obsolescence of our mobile devices (PC, smartphones but also connected objects) is now a known, worrying phenomenon and that many people are experiencing. But let’s analyze together the “why” of this obsolescence. And yet, we have a simple answer for you: the strong call of the battery. The batteries of our mobile devices are mainly lithium-ion technologies. The chemistry of those batteries leads to a certain lifespan. This lifetime is difficult to predict; the parameters influencing the battery life being numerous: charge / recharge cycle, temperature, solicitation…
