Honestly ext4 is fine for most use cases, even SSDs. If you really need more performance look at HAMMER, it’s meant for high availability. At that point you shouldn’t be running Linux anyway, even with RT_PREEMPT it’s not going to be the most performant for those kinds of RTOS workloads anyway.
HAMMER2 is now the default on DragonflyBSD. If I made a bunch of money during the boom and could spend my days doing open source (like Matt Dillon), porting HAMMER2 might be one of the projects I'd pick up.
That would be a neat project. It’s hard to set aside the time when you don’t have much in the time bank. I’ve been wanting to do a lot more research on kernel scheduling, writing my own alternative scheduler, and more research on RTOS design and real-time computing in general.
