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.
