We have a strange problem with parity after our smart contract addresses are increased. There is a scheduled process to check for the transaction records and we have web3j calls to getBalance/getTransactionCount. The calls are slow and when we analyze the issue, found that the IO wait is high on parity node.
We are using Parity-Ethereum//v2.3.2-beta-678138f-20190203/x86_64-linux-gnu/rustc1.31.1.
Is there any specific configuration to improve the IO performance?
