The average desktop user on Linux needs low latency. To get that, one must |
10 |
sacrifice some throughput efficiency. |

The average server machine needs high throughput. To get that, one must |
13 |
sacrifice some latency efficiency. |

Latency and throughput cannot both be optimal as they conflict. One must pick |
16 |
the point of the line on the graph that best suits one's needs and move |
17 |
forward from there. I have no idea what hardware you run but your replies |
18 |
indicate a high possibility of one of these: |

1. server usage |
21 |
2. Massive bleeding edge desktop hardware that can give acceptable performance |
22 |
regardless of what you throw at it. |

24 |
have you considered that there is a large population of users whose needs and |
25 |
workload are totally different from yours and therefore require something |
26 |
completely different to you? |
