We are explicit about our dependencies, so we know what code we need to run to run a specific component. Lazy-loading and bundle splitting can have a huge impact on page performance: less code requested, parsed, and executed. You can see a demo here (check the code source ). MORE
The first step towards this goal is the recently announced move of the HammerDB source code to the TPC-Council GitHub repository.

I recently improved flame graph code coloring. Code-type coloring was a regex hack that took five minutes.

I usually precede the code that I want to test with a “warm-up” loop consisting of at least a few seconds of execution of instructions using the same SIMD width as the code that I want to test. This is even more confusing when you consider vectorization and loop unrolling, which the compiler may change significantly from one compilation to the next as you fiddle with your code. For simple loops, you can look at the assembly code and count instructions. MORE
Sometimes code turns ugly. We add quick fixes or enhancements and our code starts to become a big tangle of functions that aren’t laid out in any sort of organized fashion. Over time, our code becomes bloated, difficult to maintain and what should be simple little fixes can quickly turn into long walks through messy syntax. By using the system applied to coding, we can make our code more efficient and much easier to maintain. MORE
