geth Clique PoA benchmarking

To have a nodes setup comparable to the quorum 7nodes example or the blk.io crux-quorum-4nodes-docker-compose, I am looking for a ready dockerized or vagrant virtualbox solution. Please tell me if you know a good one. For now I have chosen

javahippie/geth-dev

git clone https://github.com/javahippie/geth-dev javahippie_geth-dev
cd javahippie_geth-dev

edit both duplicates of the genesis block

nano node/genesis.json 
nano miner/genesis.json

and change to these values (faster & larger blocks):

    "clique": {
      "period": 2,
    }
  },
...
  "gasLimit": "0x2625A00",

(unfortunately, 1 second period, and 20million (0x1312D00) gasLimit (like in my quorum IBFT benchmarks) seems to not work properly here (chain stuck) - so I chose twice the interval and blocksize)

then start with

docker-compose up

At http://localhost:3000/ you can see an ethstats overview of the three nodes.

docker stuff

If any changes in those ^ files are not reflected after restarting - try:

docker-compose build

N.B.: It can take quite some time after restarting, until a new block is created. Before starting a benchmarking, I suggest to always open a JSRE console, and check that the blocknumber is increasing:

geth attach http://localhost:8545
eth.blockNumber

To delete the blockchain and start new

docker-compose down
docker-compose up

Also see this issue.

results approx 350 TPS but only for first 14k transactions

The following averages are calculated in the zoomed in diagrams at the bottom of notebook chainreader/blocksDB_analyze_geth-clique.ipynb

  • we see approx 350 TPS when averaging over blocks 23-40
  • then a sudden drop, after ~14,000 transactions (also visible in TPS_current in the above table)
  • we see approx 230 TPS when averaging over blocks 44-53

The reason for this drop is to be found out, see issue GE#17447 "Sudden drop in TPS after total 14k transactions".

(actually, same behavior as in quorum IBFT)

issues

  • GD#13 chain is stuck at block 1 or block 2
  • GD#14 account password?
  • GD#15 remove chain without rebuilding whole container
  • GE#17447 Sudden drop in TPS after total 14k transactions
  • GE#17535 how to detect which consensus algorithm is driving the chain?
