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

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

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

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

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