I'm working on a bare metal project for the Raspberry Pi 4 that is not exactly an operating system but has a lot in common with a traditional kernel. At the moment this project is nothing more than a graphics library stub and is already pretty slow, so following advice that I got on the Raspberry Pi forums I benchmarked it and was negatively impressed by the numbers, especially the fill rate numbers, where I didn't expect any problems since that's just writing to a small tile in memory and at least in theory I should be hitting the L1 cache all the time.
In case someone is interested in taking a look, I've made the benchmark code available.
