I understand that very well. But non of the standard tools that manage CPU understand that, and most people don't either.
If I had a nickel for every time I had to explain why "You are at 50% CPU now, but you can't actually run twice as many processes on this machine and get the same runtime", I'd be able to buy a large frapuccino or two at starbucks.
Perhaps I'm uninformed though - is there a tool like htop, which would give me an idea of how close am I to maxing out a CPU?
- pertymcpert 7y agoNo there isn’t. But if you understand it I don’t get why you think 20% isn’t a good performance boost, especially considering the rate of return for power and area in silicon.
- beagle3 7y agoBecause many people believe it is a 100% improvement, plan/budget accordingly, and then look for help. As far as silicon/power it is nice, but IIRC (I am not involved in purchasing anymore) it used to cost over 50% in USD for those 20% in performance when you non-HT parts were common.
- pertymcpert 7y agoWhat a strange way to measure the benefits of a performance optimization: "how people will perceive it and then ask me for help".
- beagle3 7y agoYou ignored the price issue, which was measurable and real, but also: It (used to be) my job. Does "because people fall for deceptive marketing, waste money, and then waste my time trying to salvage their reputation" sound better?
