Node Sync Speed Benchmarking Tool

WHAT IT DOES The Node Sync Speed Benchmarking Tool is an analytics tool that measures the sync speed of your connected Ethereum node by tracking block number progression over time. It samples the node's latest block number at configurable intervals, calculates the rate of block advancement, and provides detailed performance metrics. The tool also measures RPC response times, giving insights into node responsiveness and network latency. This helps node operators, developers, and infrastructure teams evaluate node performance, identify bottlenecks, and ensure their nodes are keeping up with network activity. HOW TO USE Connect your wallet to establish an RPC provider connection. Configure the sample interval (default 5 seconds) and the number of samples to collect (default 10). Click "start benchmarking" to begin collecting block number samples. The tool automatically collects samples at the specified interval, tracks block progression, and calculates sync speed. Results include total time elapsed, blocks progressed, sync speed in blocks per second, RPC response time statistics (average, min, max), and a performance assessment with recommendations. A progress table shows the sync rate over time, helping identify periods of high or low performance. TECHNICAL MECHANISM The tool uses the connected RPC provider to fetch the latest block number using eth_blockNumber via ethers' getBlock('latest') method. Each sample captures the block number and the RPC response time in milliseconds. The tool collects samples at user-defined intervals using setTimeout-based recursion. After collecting the specified number of samples, it calculates key metrics: total time elapsed between first and last sample, block difference between first and last block numbers, and sync speed as blocks per second. The tool also computes average, minimum, and maximum RPC response times to measure provider latency. A progress table is generated showing block advancement at each interval, with calculated speed between consecutive samples. The tool provides a performance assessment based on sync speed thresholds: excellent (>1.5 blocks/sec), good (0.8-1.5 blocks/sec), moderate (0.3-0.8 blocks/sec), and slow (
