-Let’s talk about memory usage specifically. It is hard to measure memory in a
-way which is accurate or meaningful. An in-depth understanding of how paging
-and virtual memory work in your operating system is required. Furthermore, even
-if we had a well-defined way of displaying memory usage and you would
-understand it, I think that it’s not helpful to repeatedly monitor your memory
-usage. One reason for that is that I have not run out of memory in the last few
-years. Memory has become so cheap that even in my 4 year old notebook, I have
-8 GiB of RAM. Another reason is that your operating system will do the right
-thing anyway: Either you have not enough RAM for your workload, but you need to
-do it anyway, then your operating system will swap. Or you don’t have enough
-RAM and you want to restrict your workload so that it fits, then the operating

-For CPU frequency, the situation is similar. Many people don’t understand how
