I'm aware, but alas in my domain anything above 50us is "noticeable" if it happens regularly

  HFT?

    Something like that yes

  It might be a noticeable delay if you require quick response by the program, but won't have a significant impact on the total run time of the program.

    It depends on your requirements. Some domains might state a worst case for a single transaction or percentage of transactions that definitely exceeds what can be achieved here

      Ada with the Ravenscar profile enabled is a good choice for such scenarios. Together with a real-time operating system it allows you to satisfy hard real-time guarantees. As you certainly know, though, hard real-time constraints require hardware validation.

        Yea, for a lot of requirements hard realtime isn't necessary and at least some older linux systems can be tuned to remove almost all jitter giving very good 99.9th percentile figures. I've even seen it done with zero alloc java
