Haiku activity report: performance edition

Now that Haiku has entered the beta phase, and after the work over the past year or so spent fixing the majority of known kernel crashes and other general instabilities, it is high time we start paying more attention to the whole system’s performance. Despite how “snappy” Haiku seems, most of its internals are really not so well optimized. This shows when running operations of any real intensity (disk, memory, or CPU.) While the new thread scheduler a few years ago removed some of the thread-related bottlenecks, in practice this just shifted the load to other bottlenecks. So, let’s take an overview of this past month’s (and some earlier month’s) changes, to see how one optimizes an operating system. Haiku always feels very fast and snappy, but in reality, many of us have that perception because we tend to not really use Haiku as much as we use Windows or Linux. I’m really glad the Haiku team acknowledges this, and is looking to address low-level performance issues that may not look sexy in a changelog, but that are oh so crucial for the overall feel of the operating system.
