Apart from library code, maybe your application doesn't have frame pointers either, in which case everything is broken. I'm sure this delivered large performance improvements and I wouldn't try arguing against it. This is exactly what happened on Linux, not just /usr/bin but also /usr/lib and application code!

The division by a power of two ( / (2 N )) can be implemented as a right shift if we are working with unsigned integers, which compiles to single instruction: that is possible because the underlying hardware uses a base 2. I make my benchmarking code available. What if d is a constant, but not known to the compiler? Can we do better?

Now welcome to the hardware jungle. From 1975 to 2005, our industry accomplished a phenomenal mission: In 30 years, we put a personal computer on every desk, in every home, and in every pocket. In 2005, however, mainstream computing hit a wall. The free lunch is over. Galaxy S II, Droid X2, iPhone 4S). There’s no going back.

Be sure to deploy SQL Server 2017 CU6 or newer for best data durability and performance results. “. The “forced flush” changes in SQL Server avoid flushes, when possible, in order to improve performance on non-optimized Fua file systems.

If they are higher than your CPU count, then you might have a performance problem (it depends). Nowadays, the source code to old operating systems can also be found online. Linux is also hard coding the 1, 5, and 15 minute constants. The oldest change in the entire Linux repo dates back to 2005, when Linus imported Linux 2.6.12-rc2,
