推荐答案
这意味着您的工作量被JMH中断了，很可能是因为它超出了迭代时间.它会打印( interrupt )"，让您知道该分数是在JMH的积极干预下获得的，可能不可靠.
That means your workload was interrupted by JMH, quite possibly because it overrun the iteration time. It prints "(interrupt)" to let you know the score was obtained with active intervention of JMH, and may be unreliable.
您可以使用 @Timeout(time = 1，timeUnit = TimeUnit.HOURS)注释基准，它会花费更长的时间.默认情况下，当您运行某些批量测量(未设置时间限制)时，它将默认为10分钟的时间限制.
You can annotate your benchmark with @Timeout(time = 1, timeUnit = TimeUnit.HOURS) annotation and it will know that it will take longer. By default when you run some batch Measurement (without time limit set), it will default to 10 minutes time limit.
