Build Qitmeer-DAG Network

How to quickly run the Qitmeer-DAG Network, see here.

Run miner

How to quickly run a miner, see here.

Test Step

  • Configure the test environment
  • Create accounts(addresses and private keys)
  • Run Qitmeer-DAG nodes
  • Configurate miner
    Configure the address of the sending transaction account to the mining address:
./hlc-miner -s 47.93.20.102:1236 -u test -P 123 --symbol PMEER --notls -i 24 -W 256 --mineraddress TmN4SADy42FKmN8ARKieX9iHh9icptdgYNn --testnet

The following parameters can be modified depending on your situation:

s :full node IP and port
mineraddress: miner account address
u : full node rpc username
P : full node rpc password
  • Mining to the send transaction account: 60 blocks, 1500 PMEER
  • Create 43,956 signed RAW transactions through scripts and export them to CSV files

Create sign raw transaction hash script

  • Configure the test client(JMeter), Key configuration parameters:

    Number of Threads (users): 2200
Ramp-Up Period (in seconds): 2
Loop Count: 10

JMeter parameters LoopController.loops=10, It is the number of transactions sent on behalf of a thread. ThreadGroup.num_threads=2200, It is the number of threads opened. The product of the two is the number of transactions sent this time.

  • JMeter loads CSV files and sends RAW transactions to the test network by calling the sendRawTransaction RPC of the miner's full node. JMeter configures 2200 threads to send them, recording the start time of sending transactions.
  • Look at the miner log, observe the packing block situation of the transaction, record the time when the first empty block appears, and when more than three empty blocks appear in a row, we can think that the transaction has been processed, and take the first empty block time as the end time.
  • View the total number of transactions through the logs of the miner
  • TPS is calculated by dividing the total number of transactions by the test time. TPS = Number of Successful Transactions /(Completion Time - Start Transaction Time)

Transactions and Blocks log

There are two miner, the transactions and blocks logs of the miner one is:

It can be seen that a total of 43955 transactions have been sent, which takes 00:02:15, which is 135 seconds, and the transaction transmission speed is 326 transactions/s.

Test result

Number of transactions/sec: numberOfTransactionPerSecond

Response time in ms: responseTimeInMs

CPU and Memory of Full node(miner connected) : cpuMem

According to the steps described above, three tests, taking the average of three results, the final results are as follows:

num of TXs send rate success % num of blocks duration TPS
43,956 662.2/s 99.998% 44 135s 326

Conclusion

During the test, different transmission rates were used and different transaction volumes were tested. The test results TPS reached more than 326.

TPS is very related to the following two configurations:

  1. The maximum number of transactions in a block (block sizes)
  2. The average block time
