12. xchain性能测试使用文档¶
这里介绍一下使用xbench工具进行xchain性能测试的方案。
12.1. 测试拓扑¶
xchain 由三个独立机器节点组成，xbench从另1台机器发压到1个node节点
node节点机器硬件配置
cpu：Intel(R) Xeon(R) Gold 6148 CPU @ 2.40GHz 160核
硬盘：nvme 7.1T*6
内存：1510G
系统：CentOS release 6.3 (Final)
内核：3.10.0_3-0-0-22 x86_64
句柄数：10240
网卡：Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection
测试环境-网络参数
平均时延：21.915 ms
抖动：0.166 ms
下行带宽：272 Mbits/sec
上行带宽：1.24 Gbits/sec
12.2. 环境搭建¶
12.2.1. xuperchain网络搭建¶
下载xchain，并编译。
git clone https://github.com/xuperchain/xuperchain.git
cd xuperchain
make
cp -r output node*
# 重复上述步骤，在node1，node2，node3上编译xchain
生成矿工地址和网络地址
cd node*
rm -rf data/keys && rm -rf data/netkeys
./xchain-cli account newkeys
./xchain-cli netURL gen
# 重复上述步骤在node1，node2，node3上生成矿工地址和网络地址
修改各node port配置：conf/xchain.yaml
node1 如下:
tcpServer:
port: :17101
p2p:
port: 27101
node2 如下:
tcpServer:
port: :17102
p2p:
port: 27102
node3 如下:
tcpServer:
port: :17103
p2p:
port: 27103
获取矿工地址和网络
get neturl
node1_neturl: ./xchain-cli netURL preview --port 27101
node2_neturl: ./xchain-cli netURL preview --port 27102
node3_neturl: ./xchain-cli netURL preview --port 27103
get address
node1_address: cat node1/data/keys/address
node2_address: cat node2/data/keys/address
node3_address: cat node3/data/keys/address
修改node2、node3的bootnodes配置：conf/xchain.yaml
因为node1为bootnode，地址为步骤3中node1的neturl
p2p:
bootNodes:
- "/ip4/<node1_ip>/tcp/<node1_p2p_port>/p2p/<node1_hash>"
修改各node data/config/xuper.json配置
地址为步骤3中node1/node2的address和neturl
"predistribution": [
{
"address": "node1_address",
"quota": "100000000000000000000"
},
{
"address": "node2_adress",
"quota": "100000000000000000000"
}
]
"genesis_consensus": {
"name": "tdpos",
"config": {
"timestamp": "1559021720000000000",
"proposer_num": "2",
"period": "3000",
"alternate_interval": "3000",
"term_interval": "6000",
"block_num": "20",
"vote_unit_price": "1",
"init_proposer": {
"1": [
"nEnyPKZrgSJfhuoccWTUjJnK4o3wEhpiY","Z4aCZJ5yWN3KECdDGbQ6BAtCYkxYLvPwG"
]
}
"init_proposer_neturl": {
"1": [
"/ip4/10.117.131.15/tcp/27101/p2p/Qme97v89162zZw55Nu4pAmuFg1ccabDQeXzZ5exeQzF56X",
"/ip4/10.117.135.37/tcp/27102/p2p/QmPaC7MVdNCQEiyF1ZgLYLM4rKSoVzRLVPdRSyzaaAnjHP"
]
}
}
日志配置修改：conf/xchain.yaml
关闭console输出，日志级别调为warn
log:
console: false
level: warn
启动底链网络
./xchain-cli createChain --host node*_ip:port
nohup /home/xbench/apps/xuperchain/node*/xchain &
# node1，node2,node3 重复上述步骤启动
检查底链网络正常启动
./xchain-cli status -H=node1_ip:port|grep Height
# node1\node2\node3高度一致，说明底链启动成功
编译合约
编译counter合约&实名合约：
cd ./core/contractsdk/cpp
./build.sh
cp ./core/contractsdk/cpp/build/counter.wasm /xbench/output/counter.wasm
cp ./core/contractsdk/cpp/build/identity.wasm /xbench/output/unified_check.wasm
12.2.2. 压测环境配置¶
建合约账户/合约用户转账
./xchain-cli account new --account 1123581321345589 --fee 1000 -H node1_ip:port
./xchain-cli transfer --to XC1123581321345589@xuper --amount 548900 -H node1_ip:port
部署实名合约unified_check和性能测试合约counter
./xchain-cli wasm deploy --account XC1123581321345589@xuper --cname unified_check -a '{"creator": "node1_address"}' unified_check.wasm --fee 155338 -H node1_ip:port
./xchain-cli wasm deploy --account XC1123581321345589@xuper --cname proftestc -a '{"creator":"node1_address"}' counter.wasm --fee 152806 -H node1_ip:port
压测bank账户转账
xbench默认压测bank账户dpzuVdosQrF2kmzumhVeFQZa1aYcdgFpN
./xchain-cli transfer --to dpzuVdosQrF2kmzumhVeFQZa1aYcdgFpN --amount 100 --keys data/keys/ -H node1_ip:port
分割bank账户utxo
./xchain-cli utxo split -A dpzuVdosQrF2kmzumhVeFQZa1aYcdgFpN -H node1_ip:port -N 100 -P xbench/output/data/ --keys xbench/output/data/keys/
