Solana RPC sendTransaction Benchmark

This repository contains a script designed to evaluate the efficiency of the sendTransaction function on a Solana RPC.

Configuration Parameters

• AUTH_KEYPAIR_PATH:
  Path to the JSON file containing your keypair.

• RPC_URL:
  The RPC URL used to retrieve block and slot information. For consistent results, use the same RPC_URL when testing different SEND_RPC_URL endpoints.

• SEND_RPC_URL:
  The RPC URL you wish to test. Maintain consistency in other parameters when testing different RPCs to ensure comparable results.

• NUM_OF_TRANSACTIONS_PER_ROUND:
  The number of transactions sent together in each round.

• NUM_OF_ROUNDS:
  The total number of rounds to run during the test.

• COMPUTE_UNIT_LIMIT:
  The compute unit limit set for each transaction.

• COMPUTE_UNIT_PRICE:
  The price per compute unit set for the transactions.

• NUM_OF_SPAM_PER_TX:
  The number of times to send an individual transaction to the same rpc.

Usage

Before running the script, ensure that all configuration parameters are set according to your testing requirements. Rename .env.example to .env, adjust the parameters as needed.

To execute the script, use the following command:

npm install
npm run start

Example output

Round 0: Tx sent: 20, Tx landed: 3, landing rate: 0.15
Average slot gap: 8, Min slot gap: 8, Max slot gap: 8
Round 1: Tx sent: 20, Tx landed: 0, landing rate: 0.00
Average slot gap: NaN, Min slot gap: Infinity, Max slot gap: -Infinity
Round 2: Tx sent: 20, Tx landed: 3, landing rate: 0.15
Average slot gap: 16, Min slot gap: 3, Max slot gap: 42
Round 3: Tx sent: 20, Tx landed: 2, landing rate: 0.10
Average slot gap: 38.5, Min slot gap: 37, Max slot gap: 40
Round 4: Tx sent: 20, Tx landed: 0, landing rate: 0.00
Average slot gap: NaN, Min slot gap: Infinity, Max slot gap: -Infinity


Overall: Tx sent: 100, Tx landed: 8, landing rate: 0.08
Average slot gap: 18.625, Min slot gap: 3, Max slot gap: 42
