UPDATE - I realized that the below test is not valid because in the case of 12VPN Twelve for Chrome extension, the data stream was actually bypassing the proxy and testing my ISP directly. This should not happen on an html5 speed test. I have contacted the support staff of 12VPN and will try to investigate the cause of this and do another test if I can get 12VPN proxy to not bypass the proxy during the speed test.
Please disregard the test results from 12VPN Twelve for Chrome. I will leave the results here as a reference for VPN.AC SecureProxy speed and latency.
Today I am testing VPN.AC Secure Proxy vs 12VPN "Twelve for Chrome" browser extensions for Google Chrome. Google Chrome only allows one extension to control the browser proxy settings so I had to install each one in a separate Google Chrome profile. I tested one Asian server, one US west coast server, and one European server for each service.
If you want to try either of these there is a special discount available for visitors of this website. You can try both risk-free because VPN.AC has a 7 day money-back garauntee and 12VPN has a 14 day money-back guarantee. For 12VPN the money back garauntee is only available if you pay with a credit card or Paypal (not valid for Alipay or Bitcoin). If you want to use a Chinese bank card to pay for 12VPN do it via Paypal. For VPN.AC I am not aware of any restriction on the money back guarantee. It should be available for all payment methods including Alipay and Bitcoin.
If you want to try your own testing with a proxy such as VPN.AC Secure Proxy, 12VPN Twelve for Chrome, 12VPN VPNGUI, or Astrill OpenWEB remember to use an html5 speed test such as speedtest.dslreports.com and not a flash based test such as speedtest.net. Flash will bypass web proxies so you are only testing the speed from your ISP directly, the traffic will not go through the proxy. If you are using VPNGUI from 12VPN use "OpenWEB" and not "OpenWEB China" because "Open
WEB China" will bypass the proxy even with an html5 test. If you are using Windows 7 you can check the Resource Monitor to make sure the speed test traffic is being routed through the proxy. The resource monitor can be found in the Windows Task Manager, Performance tab.
