成功跑完caliper自带例子之后，本人尝试使用caliper来测试自己部署的多机fabric环境。
被测fabric网络拓扑
1orderer、3peer、kafka共识、无ca、native启动（非docker）。

遇到的问题
安装问题：
- error: [join-channel.js]: Failed to join peers, TypeError: Cannot read property 'getConnectivityState' of undefined
问题： grpc的版本错误 必须v.1.10.1 - info: [bench-flow.js]: #######Caliper Test######
(node:25548) DeprecationWarning: grpc.load: Use the @grpc/proto-loader module with grpc.loadPackageDefinition instead
问题：nodejs的版本要是8.x（不能太低也不能太高）
执行问题
- error: [Peer.js]: sendProposal - timed out after:120000
问题：超时时间设置过短。 src/fabric/e2eUtils.js里调整超时时间 -
channel已存在要设置：
image.png
- 由于是已经启动好的链码，如果已经安装上chaincode再次测试会报错，需要调整代码。可以看Pr162的解决办法，在区块链网络配置中chaincodes项加deployed参数，并且在src/fabric/install-chaincode.js文件以及src/fabric/instantiate-chaincode.js文件中加入相应的处理逻辑：
https://github.com/hyperledger/caliper/pull/162
具体：在安装初始化之前chaincodes的deployed为false:
"chaincodes": [{"id": "simple11", "path": "contract/fabric/simple/go", "language":"golang", "version": "v2", "channel": "mychannel","deployed": false}],
安装成功后再执行的时候 chaincodes的deployed为true
"chaincodes": [{"id": "simple11", "path": "contract/fabric/simple/go", "language":"golang", "version": "v2", "channel": "mychannel","deployed": true}],
其他问题可以在https://github.com/hyperledger/caliper/issues 查找
fabric性能影响的要素
- 交易复杂度
- solo/kafka
- 出块时间&&出块交易个数
- leveldb/couchdb
- 机器cpu、内存资源
- 网络拓扑部署情况
- ...
