Overview

The iperf package is designed to facilitate network performance testing using the iperf3 tool. with both UDP and TCP over IPv4 and IPv6.

Configuration

• Name: iperf
• Schedule: 4 times a day
• Jitter: 20 min

Details

• The package using the iperf binary to examine network performance under different conditions.
• It randomly fetch PublicConfig data for randomly public nodes on the chain + all public node from free farm. These nodes serve as the targets for the iperf tests.
• For each node, it run the test with 4 times. through (UDP/TCP) using both node IPs (v4/v6)
• result will be a slice of all public node report (4 for each) each one will include:

    UploadSpeed: Upload speed (in bits per second).
    DownloadSpeed: Download speed (in bits per second).
    NodeID: ID of the node where the test was conducted.
    NodeIpv4: IPv4 address of the node.
    TestType: Type of the test (TCP or UDP).
    Error: Any error encountered during the test.
    CpuReport: CPU utilization report (in percentage).
