Without an understanding of memory management, OS level task and thread scheduling, and even in some cases disk management, it is impossible to consistently write high performance code. This is especially true in garbage collected languages such as any dotNet language, Java, and even javascript. This lack of understanding memory allocations and management leads to poor design decisions making code that simply cannot scale without adding hardware.

Even business programmers, which I am, need to understand memory management to guide in the selection the correct data structures to ensure their applications are responsive and low impact on the user PCs. A perfect example was at my last job where we used OpenVMS running on a dual processor Alpha Server. We had an incredibly long and somewhat complex overnight processing script that needed to be complete by 6 AM every morning. As our data grew it was taking until close to 7 AM on some mornings. Using my general knowledge of task scheduling, disk performance, and CPU utilization I was able to rewrite the longest component of this process to partition that part of the problem into independent units and then submit those units for processing. Then I monitored disk I/O and CPU load to find the optimum number of simultaneous job partitions that could be run and set the VMS queue to allow that many jobs to run at one time. These changes cut three to four hours of our nightly processing time. Without my knowledge of system resource usage this simply wasn't possible and my boss, who actually wrote the application software, didn't think we could shorten the overnight processing time and was thinking about adding hardware.
