Load balance distribution across different numbers of machines.

The maximum and minimum load refer to the average load of VMs with the largest and smallest loads (in terms of percentage of files processed) over five trials. The p-value is derived from a single-factor ANOVA test. p ≤ 0.05 indicates, with 95% confidence, that processing loads are not equal.最大负载与最小负载指的是，在五次试验中，负载最高与最低的虚拟机（Virtual Machines, VMs）的平均负载（以已处理文件占比作为衡量标准）。p值源自单因素方差分析（Analysis of Variance, ANOVA）检验。当p值≤0.05时，即可在95%置信水平下认定处理负载并不相等。
