Algod API calls rate limit on local node

post by Skiny on Feb 10, 2025

Hi, I am testing my smart contract and I am performing a stress test with my local node. I am sending (using the go-algorand-sdk) around 1000 transactions in batches each round. But I get errors like:

Post “http://0.0.0.0:4190/v2/transactions”: dial tcp 0.0.0.0:4190: connect: connection reset by peer

and

Post “http://0.0.0.0:4190/v2/transactions”: dial tcp 0.0.0.0:4190: connect: can’t assign requested address

If I keep the batches in 100, all is fine, but anything higher than that will give me errors.

My node config is this:

{
  “EndpointAddress”: “0.0.0.0:4190”,
  “RestConnectionsSoftLimit”: 10240,
  “RestConnectionsHardLimit”: 40560,
  “TxBacklogAppTxPerSecondRate”: 10000,
  “TxBacklogRateLimitingCongestionPct”: 75,
  “EnableTxBacklogAppRateLimiting”: false,
  “EnableTxBacklogRateLimiting”: false,
  “TxBacklogSize”: 52000,
  “TxPoolSize”: 375000,
  “DisableLocalhostConnectionRateLimit”: true
}

Any ideas on how can I increase the API calls limit on my node?
