Structs are great for controlling memory layout and avoiding the GC, but we can go a lot further to get even more speed out of them. Today we’ll look at a simple tweak that can dramatically speed up the code using the structs without even changing it!
Last week’s article introduced two new native collection types:
NativeLongPtr. These were useful for both
IJobParallelFor jobs, but performance was degraded in
IJobParallelFor. Today we’ll remedy that, explore some more aspects of Unity’s native collection and job systems, and learn more about CPU caches along the way.
The last time we looked at performance was way back in part four of the series. Ever since then we’ve been relentlessly adding more and more features to the C++ scripting system. So today we’ll take a break from feature additions to improve the system’s performance in a couple of key areas.
Most programmers write code for an abstract computer. The thing is- code runs on a real computer that works in a specific way. Even if your game is going to run on a wide range of devices, knowing some of the common features can speed up your code 10x or more. Today’s article shows you how!
