Corda 当卷较大时，在收集签名期间性能会变慢

我试图创建大约100个线性状态。它在一个流中，每个循环只包含一个

N

子流另一个

IssueFlow

，每个发送发出一个状态。 这是在Corda 3.0、Azure云上使用的

Intel（R）Xeon（R）CPU E5-2673 v3@2.40GHz 4GB RAM

线性状态包括

借贷者

贷款人

调节器

在签名过程中，在前40~50个状态中，每个参与者大约需要3~4秒才能做出响应。但随着时间的推移，启动器接收响应可能需要14秒以上的时间。为什么随着容量的增加，性能会下降

总持续时间的基准如下所示

10个州~2.5分钟

50个州~30分钟

100个州~105分钟

在这里的示例日志中，您可以看到启动器在collect签名中处理参与者响应最多需要16秒

与贷款人的开始时间：2018-06-29T11:07:56356Z

贷方终止时间：2018-06-29T11:08:12669Z
