Altius Benchtools

This is a collection of tools for Altius benchmarking, featuring a profiler for RPC server execution tracing and a transaction_generator for Ethereum test cases.

1. Profiler

A tool for tracing and profiling RPC server execution with detailed timing and event tracking capabilities.

Features

• Task timing with start/end markers
• Multi-threaded profiling support
• Event annotation with notes and descriptions
• JSON and ZIP output formats
• Special handling for transaction and commit events

Usage

// Start timing a task
profiler::start("task_name");

// ... your code here ...

// Add notes to the current task
profiler::note_str("task_name", "key", "value");

// ... your code here ...

// End timing a task
profiler::end("task_name");

// Export results
profiler::dump_json("output.json");
// or
profiler::dump_zip("output");

Multi-threaded Usage

The profiler supports concurrent operations across multiple threads:

// In any thread
profiler::start_multi("thread_task");

// ... your code here ...

// In any thread
profiler::note_str_multi("thread_task", "thread_info", "worker_1");

// ... your code here ...

// In any thread
profiler::end_multi("thread_task");

// ... your code here ...

// Export results
profiler::dump_json("output.json");
// or
profiler::dump_zip("output");

Output Format

The profiler generates a JSON structure containing:

• Timing information for each task
• Thread identification
• Custom annotations and notes
• Transaction and commit event details

An example of the output JSON is as follows:

{
  "details": [
    {
      "detail": {
        "hash": "0x26b7c694ff75f0b4ee85b5ca2e3cc1c332b41a64982c2b454e0493497b8e76b9",
        "type": "transaction"
      },
      "end": 212387237,
      "runtime": 31286,
      "start": 212355951,
      "status": "success",
      "tx": "125",
      "type": "transaction"
    },
    {
      "detail": {
        "hash": "0xbc3d47d6c7df3430c8c88e0e6b28204185d3a7aab0fb7f8464e2b28b0d79d1bd",
        "type": "transaction"
      },
      "end": 232170705,
      "runtime": 163541,
      "start": 232007164,
      "status": "success",
      "tx": "125",
      "type": "transaction"
    },
    {
      "detail": {
        "hash": "0x255cd19c2bad53734fc8c6df7e5b6f74a85733183b9cb9bcbf1e16de9404d87d",
        "type": "transaction"
      },
      "end": 255598060,
      "runtime": 28209,
      "start": 255569851,
      "status": "revert",
      "tx": "125",
      "type": "transaction"
    },
    { "...": "..." }
  ],
  [ "..." ]
}

2. Transaction Generator

This tool generates a JSON file containing a list of transactions and a pre-state of the blockchain.

Usage

1. Run cargo build --release to build the project.
2. Run ./target/release/generate --help to see the available options.

ETH-transfer Usage

After building the project, you can use the following commands to generate test cases.

• Generate a JSON file with 100 ETH-transfer transactions in 10 groups, using the one-to-many pattern, and save it to ./test-case.json.

  ./target/release/generate pattern -y o2m -t 100 -g 10 -o ./test-case.json
  # or
  ./target/release/generate pattern -y one-to-many -t 100 -g 10 -o ./test-case.json
  

• Generate a JSON file with 200 ETH-transfer transactions in 5 groups, using the chained pattern, and save it to ./test-case.json.

  ./target/release/generate pattern -y chained -t 200 -g 5 -o ./test-case.json
  # or
  ./target/release/generate pattern -y ring -t 200 -g 5 -o ./test-case.json
  # or
  ./target/release/generate pattern -y chain -t 200 -g 5 -o ./test-case.json
  

• Generate a JSON file with 100 ETH-transfer transactions with 60% conflict rate, and save it to ./test-case.json.

  ./target/release/generate pattern -y m2m -t 100 -c 0.6 -o ./test-case.json
  # or
  ./target/release/generate pattern -y many-to-many -t 100 -c 0.6 -o ./test-case.json
  

ERC20-transfer Usage

Directly use the erc20 flag to generate ERC20-transfer transactions. Other options are the same as ETH-transfer.

• Generate a JSON file with 100 ERC20-transfer transactions in 10 groups, using the one-to-many pattern, and save it to ./test-case.json.

  ./target/release/generate pattern -y o2m -t 100 -g 10 -o ./test-case.json --erc20
  # or
  ./target/release/generate pattern -y one-to-many -t 100 -g 10 -o ./test-case.json --erc20
  

• Other options are the same as ETH-transfer.

Output Format

The output JSON file is a list of transactions and a pre-state of the blockchain.

An example of the output JSON is as follows:

{
  "just-test": {
    "_info": { "...": "..." },
    "env": { "...": "..." },
    "post": {
      "Cancun": { "...": "..." }
