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
