Memory might be durable, but… …it is expected that caches and registers will remain volatile. Moreover, for better performance, the processor may change the order in which writes reach the NVRAM, making it difficult for the NVRAM to even reflect a consistent prefix of the computation. Performance evaluation.

Not only is the integer comparison operation cheap, but min and max are already being accessed by this function and so they’re already “hot” in registers or cache. Example 1(a)’s min <= max is at this other end of the scale: It’s so dirt cheap to check that it’s unlikely we’ll ever have a performance reason to disable it. [2]

The Problem Of Unpredictable Performance. At the same time, we have a widening performance gap. In terms for performance, these phones have plateaued at the performance of a 2012 iPhone. Applications built for the Web are expected to run on devices that fall anywhere on this broad performance spectrum.

I also compare them with stored procedures, mainly focusing on differences in terms of default optimization strategy, and plan caching and reuse behavior. In our case, the plan performs a seek in the supporting index you created earlier. In my examples I’ll use a sample database called TSQLV5. plan_handle , Q. execution_count , T.

The recently revealed [Meltdown and Spectre] bugs are not just extraordinary issues of security, but also performance. The patches that workaround Meltdown introduce the largest kernel performance regressions I've ever seen. Some older kernels have the KAISER patches for Meltdown, and so far the performance overheads look similar.

In a previous post , we described how our TV application consists of a C++ SDK installed natively on the device, an updatable JavaScript user interface (UI) layer, and a custom rendering layer known as Gibbon. Our UI runs on top of a custom rendering engine which uses what we call a “surface cache” to optimize our use of graphics memory.
