When running download tests with testmy.net I observed the payload of the test packets are all 0's & 1's which is highly compressed by our gateway/routers/proxies. Because of this we see unrealistic rates which does not match with our network link capacity. Also, more importantly I observed the http response from testmy.net does not contain the "no-transform" directive which if present would have notified the intermediate proxies to not compress/modify the test packets. Is there any plans to update your http responses with "no-transform" directive?
Simple, to make sure you're getting what you pay for. This speed test is useful if you feel a connection slow down or want to see how your Internet is performing. This isn't like any other broadband speed test. TestMy's proprietary method is proven to help identify issues other speed tests fail to detect. The TMN Speed Test shows your true speed.
