I created an Alibaba Cloud Anycast EIP to see how big of an improvement it can have compared to my Singapore EIP. It is impressive to see how it has a negative impact on the global latency department.
* Test result only applies to today at this moment. Origin server (SLB) in Singapore.
Anycast EIP
Using their own benchmark method from Tokyo server: (https://www.alibabacloud.com/help/doc-detail/171864.htm#title-mk4-1or-ni4)
# curl -o /dev/null -s -w "time_connect: %{time_connect}\ntime_starttransfer: %{time_starttransfer}\ntime_total: %{time_total}\n" "Anycast EIP"
time_connect: 0.081
time_starttransfer: 0.167
time_total: 0.167
Normal Singapore EIP
# curl -o /dev/null -s -w "time_connect: %{time_connect}\ntime_starttransfer: %{time_starttransfer}\ntime_total: %{time_total}\n" "Singapore EIP"
time_connect: 0.076
time_starttransfer: 0.152
time_total: 0.153
