增加 CPU 会影响平均负载吗?

例如,我有一个 16 核 CPU,平均负载为 10。如果我将 CPU 升级到 32 核,并且(相同的流量、相同的负载、相同的一切),平均负载应该下降还是保持不变?

答案1

理论上,当你添加更多核心时它应该保持不变,因为负载来自 wiki:


Interpretation

For single-CPU systems that are CPU bound,
 one can think of load average as a measure of system utilization
 during the respective time period. For systems with multiple CPUs,
 one must divide the load by the number of processors in order to 
 get a comparable measure.

所以我认为负荷不应该减少
