Unless you're multitasking, the OS on a separate thread gets you about 5-10% speedup. It's not really noteworthy.
Unless you lived through the 1990s I don't think you understand how fast things were improving. Routine doubling of scores every 18 months is an insane thing. In 1990 the state of the art was 8mhz chips. By 2002, the state of the art was a 5ghz chip. So almost a thousand times faster in a decade.
Are chips now a thousand times faster than they were in 2015? No they are not.

- klodolph 2y agoWhen the parent comment says “OS on a separate thread”, they’re talking about the fact that even if your user-space workload is single-threaded, the OS has a separate set of threads, which can run on separate cores from the user thread. The P4 was famously overclocked to 5 GHz in 2003.

- bee_rider 2y agoWell, in any case, we’re only going to quibble our way down to an 500x-800x speedup, right? It was still a pretty crazy era to live through.
