Provide a brief description of the functionality you're trying to implement and the issue you are running into.

I want to perform a benchmarking/performance test against the deployed environment of ZKSync rollup built on top of Hyperledger Besu network.

Could you please help and navigate me through some best practices/patterns that can be used here? Are there any specific tools that you would suggest using?

Hello @chandranik90

Generally speaking, most of the tools/patterns that you would use for EVM chains should work just as well for Era. Consider reading through the docs to become familiar with the supported tools, differences from EVM, guides and examples.

Feel free to expand with specific questions about concrete benchmarking methods or any problems you might encounter.

HI @ly0va ,

Thank you for your answer. For the L1 performance testing, I have used Hyperledger Caliper (the network is Hyperledger Besu, IBFT). It doesn't seem the Caliper may be effective for L2 rollup. Even for the L1, Caliper didn't behave so well. I encountered various limitations like heavy parallel workers, 1 tx sender per worker, lack of RPC support (only socket), absence of a retry mechanism, lack of Besu support (only Fabric), etc.

I am going to execute not only benchmarking but load and endurance tests either on a deployed environment with an infrastructure closer to prod. So, I need to simulate thousands of parallel users sending transactions among each other with around 10-15K TPS.

As an option I want to consider K6, but not sure yet. So, would like to read the experts' opinion. Maybe there are better solutions or documented solutions that can serve as a basis for me

I'm not sure I understand why it matters that the settlement layer's execution client is Hyperledger Besu. ZKsync's sequencer interacts with the settlement layer via standard RPC calls. Its performance is not affected much by the RPC client and should be similar across any settlement layer network, using any client.

There is a loadtest already implemented in sequencer repos which you can run yourself:
zksync os or zksync era.

If you need something custom, feel free to implement it e.g. via alloy, viem or any other tools/SDKs that work with EVM chains. I don't see why K6 wouldn't work if set up correctly (although I am not familiar with it).

I will mark this as answered for now, but feel free to unmark if you have any further questions.
