# 一、安装xuperchain #

下面2选1，本文选择多机多节点

## 1.单机单节点 ##

## 2.多机多节点部署 ##

# 二、xbench #

## 1. 下载 ##

# mkdir -p ~/xuper
    cd ~/xuper
    
    
    git clone https://github.com/xuperchain/xbench.git
    cd ./xbench
    make

## 2. 测试类型 ##

Xbench 现在提供 10 种测试用例

*  **deal**: Test postTx performance in transfer. Default prepare enough TXs and sign them.
 *  **generate**: Test account transfer performance.Default create enough accounts, transfer 1 from these accounts to one test account.
 *  **relay**: Test account transfer performance. Default create enough accounts, transfer 1 to themselves using the last txid, which do not need to selectUTXO.
 *  **query**: Test contract query performance. Default deploy `counter`and invoke `increase` method to increase key, query this key to test.
 *  **invoke**: Test contract invoke performance. Default deploy `counter`,invoke `increase` method to test
 *  **querytx**: Test tx query performace. Query the previous reftxid, query the first one if reach the end.
 *  **queryblock**: Test block query performance. Query the previous pre block, query the first one if reach the end.
 *  **queryacct**: Test account balance query performance. Default transfer n to an account,
 *  **lcvtrans**: Test transfer performnce using sdk. Should deploy endorser.
 *  **lcvinvoke**: Test contract invoke perfromace using sdk. Also should deploy endorser.

# 三、测试非contract invoke 或者 contract query #

以local模式，**deal测试用例为例**

## 1. 修改配置文件 ##

cd ~/xuper/xbench/output/conf

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTMyODgxOTA_size_16_color_FFFFFF_t_70][]

config meanings:

*  gen.conf : profiling normal transfer process
 *  deal.conf : prepare transaction data before, profiling postTx process
 *  invoke.conf : profiling contract invoke process

下面以修改deal.json为例

vim deal.json

{
      //tested block chain type(xchain/fabric)
        "type": "xchain",
      //concurrent num of transaction 
        "workNum": 10,
      //working mode (local/remote)
        "mode": "local",
      //chain code name
        "chain": "xuper",
      //Encryption plugins（default/schnorr)
        "crypto": "default",
      //tested block chain ip:port
        "host": "192.168.92.129:37101",
      //test behaviors (deal/generate/invoke/query/...)
        "rounds": [
            {
              //test cases
                "label": "deal",
              //requests of every worker
                "number": [ 20 ]
            }
        ]
    }

### 2. 运行测试 ###

cd ~/xuper/xbench/output
    ./bin/xbench -c ./conf/deal.json

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTMyODgxOTA_size_16_color_FFFFFF_t_70 1][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTMyODgxOTA_size_16_color_FFFFFF_t_70 2][]

# 四、测试contract invoke 或者 contract query #

编辑./conf/invoke.json

{
        "type": "xchain",
        "workNum": 500,
        "mode": "local",
        "chain": "xuper",
        "crypto": "default",
        "host": "192.168.92.135:37101",
        "nodes": ["192.168.92.135:37101"],
        "rounds": [
            {
                "label": "invoke",
                "number": [ 1000 ]
            }
        ]
    }

在16核8G内存单节点测得

4核8G内存单节点，每次都是测得1300tps，

# 五、报错 #

## 1. 句柄数超出了系统限制 ##

panic: runtime error: invalid memory address or nil pointer dereference
    [signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x1234d40]

ulimit -a | grep 'open files'

临时修改：ulimit -n 65535  
永久修改：echo  '\* - nofile 65535' >> /etc/security/limits.conf

如果报错sudo: ulimit: command not found

则使用`sudo` `sh -c``"ulimit -n 65535 && exec su $LOGNAME"`
