您好，我创建了一个Hyperledger Fabric网络，当我一次提交一些交易建议时，该网络工作正常，但是由于我必须进行一些基准测试，因此当我以高发送速率向同伴发送多个建议时出现错误。网络具有以下元素：
- 3个组织
- 3个同伴（每个组织一个）
- 1个订购者
- 1个频道
- 1用fabric-chaincode-shim 1.4.4编译的Java Chaincode
- 链码的认可政策要求所有同行都给予肯定的答复以确认交易
全部使用以下命令在一台计算机上运行：
[Intel i7-8750H CPU @ 2.20GHz
8 GB RAM DDR4
Ubuntu 19.04，具有内核5.0.0-35-通用
Docker版本19.03.4
docker-compose版本1.21.0
用于同级和订购者的Docker容器在1.4.3版上使用Fabric映像，但是我尝试了最新，结果是相同的。
我使用Hyperledger Caliper以高发送速率提交投标，其中一些投标被同行接受（执行之间的数量有所不同，但其他投标因此错误而失败：
Transaction [901d0036b2]生命周期错误：
peer0.org1.com的提案响应错误：事务返回失败：未能提交要处理的任务
我在这里报告同行日志中的错误：

由于信息INFO 1447提示对等方未能为该提案创建新任务，可能是因为许多请求一起到达。这种考虑正确吗？有什么方法可以更改对等方可以创建的并行任务的最大数量？因为这种情况即使以100 rps的速率也会发生，我想我可以进一步提高性能。

你好，我创建了一个Hyperledger Fabric网络，当我一次提交一些交易建议时，该网络运行良好，但是由于我必须进行一些基准测试，因此在发送多个交易建议时会出错...
事务处理量取决于各种因素。超账结构中有不同的可配置参数
