Does anyone have an explanation of what is going on with my speed tests? I've been noticing this lately that I have a high middle variance, and hitting my maximum speed takes a good 3-5 seconds, then it quickly drops back off after hitting it when it nears the end of the test.
Is this considered a "good" test?
Notice the "Middle" value is 100+mbps different from my final result, and the "maximum" speed is 180+mbps different.
My question is: What causes this and is there anything on my end I can do differently to correct it?
From TWC's own speed test:
Locally on my office network, transferring between nodes instantly hits a max speed (1gbps minus TCP latency overhead, before anyone suggests that I expect to receive that kind of speed or latency remotely on these tests, I understand this relationship well and don't need to be reminded).
Is there some sort of traffic shaping going on to slowly ramp up speeds on TWC's end or could there be something wrong on my end? Is it simply a router in my path to the source server seeing a longer connection and prioritizing it, outside of my control? Does anyone have good explanations for this if it's the norm? This even happens on TWC's own speed test, as it slowly ramps up to ~200-250mbps speeds over about 10-15 seconds.
The drop off at the end is what is most interesting to me, although the slow "ramp up" to appreciable speeds is what I am affected by most. Smaller filesize downloads never even reach close to my max speed, I only hit them with the 200mb test file size. (ex. 100mb, 50mb, 25mb - Links to test results)
My local network path looks like this:
D-Link DGS-1024D 1gbps Switch
Ubiquity EdgeRouter Lite
Motorola SB6183
to Time Warner Cable 300/20 mpbs Cable Internet
Thoughts? Suggestions?
As far as I can tell my connection is good to TWC:
