curl -sL -k | bash

Copy the code above and paste to benchmarking. This script supports Intel, AMD and ARM. 32-bit and 64-bit operating system architectures both work. Popular Linux distros have been tested: CentOS, Ubuntu, Fedora, Debian,…

Standard format when benchmarking:

  1. Server Hardware Information.
  2. Network Information (MaxMind Database). This feature uses our API.
  3. Standard Performance (CPU dd, RAM dd, Disk dd and random read/write). For the random read/write test, blocks are used: 4k, 64k, 512k and 1024k. There are a total of 8 tests (4 reads and 4 writes), each time up to 15s.
  4. Geekbench v5 CPU Benchmark. If you use 32-bit architecture, this part will be ignored; in addition, if the system does not have SWAP, the script will automatically create 1 GB swap for this feature to work. The output of this feature uses our API to represent the full info.
  5. Network Outbound/Inbound Test IPv4 (iperf3). By default, IPv6 will not benchmark, if you want to enable it, use the parameter (see next section). Each iperf3 address will try up to 3 times (random port), and a maximum 10s.
  6. Network Inbound Test via http/https (each host will download a 100MB file, if more than 10s, it will automatically cancel and move to the next host).
  7. Global Latency Test (timeout 1s for each host).
  8. China Latency Test (timeout 1s for each host).


  • noio: skip Standard Performance test.
  • nogk: skip Geekbench v5 CPU Benchmark test.
  • noob: skip iperf3 test.
  • obv6: enable iperf3 IPv6 test.
  • nor4: skip iperf3 Inbound IPv4 test.
  • nor6: skip iperf3 Inbound IPv6 test.
  • noib: skip Network Inbound test.
  • nogb: skip Global Latency test.
  • noch: skip China Latency test.
  • dont: this script is written mainly for our site, by default information and results will be uploaded to If you do not want this, we respect you, add this parameter and upload function will not activate.
  • Example: curl -sL -k | bash -s — nogk (no Geekbench).
