  • Historically, Android has been “built and optimized to run with a 4 KB page size.”

    In most CPUs, dedicated hardware called memory management units (MMUs) translate addresses from what a program is using to a physical location in memory. This translation is done on a page-size basis. Every time a program needs more memory, the operating system needs to get involved and fill out a “page table” entry, assigning that piece of memory to a process. When the page size is 4 times larger, there is 4 times less bookkeeping. So, the system can spend more time making sure your videos look great, games play well, and applications run smoothly, and less time filling out low-level operating system paperwork.

    As device OEMs add more RAM “to optimize performance,” they will adopt these larger page sizes. Android 15 added system support — by refactoring the OS to be page-size agnostic — for this “increased page size, ensuring your app can run on these evolving devices and benefit from the associated performance gains.” This is supported and available to test on the Pixel 8 and Pixel 9 series. This results in performance improvements like:

    • Faster app launches: See improvements ranging from 3% to 30% for various apps.

    • Improved battery usage: Experience an average gain of 4.5%.

    • Quicker camera starts: Launch the camera 4.5% to 6.6% faster.

    • Speedier system boot-ups: Boot Android devices approximately 8% faster.

















  • Sounds a bit desperate, basically spooked by their performance in Australia.

    “In order to get the parts here, we had to really shortcut the process – whether it’s going to make one-percent difference or 50-percent difference, honestly, I cannot say,” he said.

    “Depending on what we see, it could be as bad as Melbourne, or it could be even better than Shanghai. I think FP1 the key for us; as soon as we do a lap or as soon as we go through sector one, we will know if it’s going to be like Melbourne or not.”

    “We had to bring something, we couldn’t come here with the same car as Melbourne and just hope for the best.

    “We just wanted to take as much in our control as possible. That’s just a judgement call in terms of risk management to shortcut that process.”

    When asked how the process of bringing the floor differed to that of a more usual process, Komatsu explained: “Honestly, we just relied on our aero guys and designers’ understanding to make certain modifications.

    “So certain things are geometrically different and aerodynamically different as well.

    “We just put everyone’s latest understanding, without any proof, because we had to design it, we had to release it, we had to make it – otherwise we weren’t going to make it here.

    “So, we had to do it. But then, respectively we put it in the windtunnel, to see if that idea is actually correct or not.

    “It is correct. It’s definitely the right direction. But I just don’t know how much difference it’s going to make.”
