The consensus seems to be to enable DCA only if you have an old CPU. Now my two Xeon processors are Netburst or P4 like in construction, running at 3.68 GHz. Are these considered candidates for such a modification?

I changed Add-On Congestion Control Provider from none to ctcp.
I changed Direct Cache Acess (DCA) from disabled to enabled.

Am I supposed to see some improvement?
How would I know?

Run a speed test - use same time of day with the same programs running (including background processes like software update checks or AV signature database downloads)

Compare speed before changing settings vs. after changing settings.

What's your Internet Speed?

Hi,
Yep not a whole lot of difference from win-8.1 and 10 settings and Callender's.

I just like to know how my speeds compare to other users on the same ISP in the same country.

Mostly Window Auto-Tuning seems to be a Windows 10 issue

How To Check and Quickly Fix if Windows 10 is Limiting Your Internet Speed | Next of Windows

Ran the tests the in link below (download test file in two browser windows) and I don't have the problem where the second download is faster. It's actually slower which is what it should be. (I think)

Thanks for the links,
I did switch auto tuning off and back to normal after restarting of course
Not any difference

The other link just seemed to confirm this threads content
netsh interface tcp set heuristics disabled

Worth a shot though
