Performance Test

  • Welcome to the Performance Test Homepage
  • The performance test will check the bandwidth of your Internet connection to China Education and Research Network (CERNET).

  • What this test does?
  • When you click Start Test, a file is downloaded from CERNET site that will calculate your bandwidth speed from the CERNET server. Your bandwidth speed may be affected by the following factors: being located outside of the CERNET, performing other downloads and this test simultaneously, etc.

  • Why do I want to do the Performance Test?
  • Often, users perform this test out of curiosity about what the actual throughput is to their computer from CERNET Web sites.

  • Who should I contact in the case of problem?
  • You can find the contact information form the Performance Test report. The AS number administrators are usually your network service provider. Please contact them directly.
