Xv6 is a pretty good material for OS learners, but one thing I am concerned is that how I benchmark xv6 after I developed or changed it. For example, xv6 has really simple scheduling algorithm that we easily understand, so that it may be a good idea to develop scheduling algorithm to improve xv6 performance. However, one problem I met was how should I benchmark it? Therefore, I have modified 'hackbench.c', one of the simple benchmarking program, and now it can run on xv6. So, if you need to benchmark your implementations like me, you can download and measure your system on xv6.
