Performance profiling of simple Besu eth_call

[iamhsk]

Desired Outcome

Do performance profiling across different types of eth_call. Consider for:

• simple eth_call for ERC20 balanceOf

Tasks

• [ ] Evaluate tools
• [ ] Enable performance capture. Can use java flight recording using https://besu.hyperledger.org/en/latest/HowTo/Troubleshoot/Java-Flight-Recording/. Might need to increase the stack depth.
• [ ] Analyse performance result. Try and determine where the bottlenecks are

Notes

Possible profiling tools

• Java Flight Recorder
• Yourkit
• Async Profiler
