I have been meaning to post this for a while.

After migrating to FTTH last year and doing zillions of speed tests as I think we all do when we suddenly have a fast line I noticed something very odd. Local speed tests will show full speed both down and up where international speed tests would reflect a bit different which is understandable. What was odd is that my laptop on wifi was getting consistently better speed test results than my desktop on a wired connection.

I did everything I could think of going as far as buying a USB3 Gigabit adapter to see if the desktops own adapter was somehow faulty. Nothing helped. I was on the point of doing a clean Win 7 installation.

I have never and will never recommend any of these magical “Speed up your pc” or “Speed up your internet” proggies but came across a TCP Optimizer which is extremely well documented explaining what the settings actually do.
Documentation is here: https://www.speedguide.net/articles/tcp-optimizer-4-documentation-windows-7-8-10-2012-5821#quick
Proggie can be downloaded here: https://www.speedguide.net/downloads.php
There are options of saving your current settings so you can always fall back on your old settings.

It worked for me.
 
Interesting, thanks. How much of a difference did this make?

Not a monstrous difference but certainly made my wired desktop faster than my laptop on wifi! I think the higher you linespeed the more noticeable the difference will be. I am one of those people where this type of thing bugs me to tears :)

Before: 24.22 Down, 9.67 Up

After: 59.83 Down, 12.02 Up

Thanks!
 

Yes the proggie does far far more than just disabling windows TCP/IP autotuning. I first did it the old fashioned way: netsh interface tcp set global autotuning=disabled and disabled heuristics but that made very little difference. Been using the optimised settings for about 7 months now and have had no negative effects.
 
Looks like it doesn't support Windows 10... anyone know why? Edit: Oops, looking at the old version, my bad.
