    I’m a hobby software developer and a fan of reading a lot of about physics. To me, “alpha” means an highly unstable configuation with massive amount of over optimistic excitement and just one wrong nudge will have catastrohic emmission of high energy photons and sounds. But it all decays away eventually and reaches stable state. xD

    “The kernel runs out of time to solve the NP-complete scheduling problem in time.”

    More responsiveness requires more context-switching, which then subtracts from the available total CPU bandwidth. There is a point where the task scheduler and CPUs get so overloaded that a non-RT kernel can no longer guarantee timed events.

    So, web browsing is basically poison for the task scheduler under high load. Unless you reserve some CPU bandwidth (with cgroups, etc.) beforehand for the foreground task.

    Since SMT threads also aren’t real cores (about ~0.4 - 0.7 of an actual core), putting 16 tasks on a 16/8 machine is only going to slow down the execution of all other tasks on the shared cores. I usually leave one CPU thread for “housekeeping” if I need to do something else. If I don’t, some random task is going to be very pleased by not having to share a core. That “spare” CPU thread will be running literally everything else, so it may get saturated by the kernel tasks alone.

    nice +5 is more of a suggestion to “please run this task with a worse latency on a contended CPU.”.

    (I think I should benchmark make -j15 vs. make -j16 to see what the difference is)
