Why is my realized speed so slow on my 10GB line?

[sonicjason]

I have been a Sonic customer for 3 months (Belmont, CA). For the last couple weeks, surfing the web has become painfully slow. When I run SpeedTest, I get downloads speeds of 800MB+, but that high speed is absolutely NOT actualizing during my browsing or downloading. The actualized speed is like I'm on maybe 5MB. Pages from major websites take 5–10 seconds to even start rendering in the browser, and then it takes another 5–20 seconds for the page to complete. Anybody else experiencing this?

NOTE: I have already unplugged and restarted the modem and both of my eero Max 7 routers. Plus, I just updated my 2020 iMac to OS X 15.0.1 Sequoia. No improvement.

User experience is indeed different than bandwidth test in your case.

Do you have the same problem from another computer or phone?
Have you tried your computer from your neighbor's wifi or starbucks' ?

Has it always been like that since sonic was installed, and it was better on your previous connection?

Hello,

I'm sorry to hear this. I would like to give you a call so we can pinpoint the trouble you are having here. We should definitely get to the bottom of this so we can see what's hampering your connection there. When would be the best time to call you?

Did you resolve this issue? Problems with webpages not rendering in a timely manner could be caused by DNS resolution. Modern webpages are no longer monolithic and requires a multitude of resources stored in different domains/subdomains. You may want to check what DNS server your computer is using and use a program like Steve Gibson's DNS Benchmark to evaluate how your configured resolver performs over others, including Sonic's: 50.0.1.1 and 50.0.2.2. You need to manually add Sonic's resolvers to his program.

You would typically have your gateway configured to be a proxy so your local computers would use your router to act as a DNS server. For hostnames it doesn't know about it forwards that query to upstream servers like Sonic's or the more popular ones like 1.1.1.1, 8.8.8.8, etc. Whatever your router resolves should be saved in its cache saving future lookups from contacting upstream servers. Your computer should also have its own cache. The DNS performance should improve when you go there after the first time. If it does not there's something more going on that warrant deeper investigation.
