This benchmark is designed to stress test the rpc methods of a lotus node so that we can simulate real world usage and measure the performance of rpc methods on the node.
This benchmark has the following features:
* Can query each method both sequentially and concurrently
* Supports rate limiting
* Can query multiple different endpoints at once (supporting different concurrency level and rate limiting for each method)
* Gives a nice reporting summary of the stress testing of each method (including latency distribution, histogram and more)
* Easy to use
To use this benchmark you must specify the rpc methods you want to test using the --method options, the format of it is:
--method=NAME[:CONCURRENCY][:QPS][:PARAMS] where only METHOD is required.
Here are some real examples:
lotus-bench rpc --method='eth_chainId' // run eth_chainId with default concurrency and qps
lotus-bench rpc --method='eth_chainId:3' // override concurrency to 3
lotus-bench rpc --method='eth_chainId::100' // override to 100 qps while using default concurrency
lotus-bench rpc --method='eth_chainId:3:100' // run using 3 workers but limit to 100 qps
lotus-bench rpc --method='eth_getTransactionCount:::["0xd4c70007F3F502f212c7e6794b94C06F36173B36", "latest"]' // run using optional params while using default concurrency and qps
lotus-bench rpc --method='eth_chainId' --method='eth_getTransactionCount:10:0:["0xd4c70007F3F502f212c7e6794b94C06F36173B36", "latest"]' // run multiple methods at once`,
