Connection divided by two in normal mode

Hey everyone

My speedtest in safe mode is at 960 mbps
My speedtest in normale mode is at 400 mbps


I know that it's a good connection anyway but i want to enjoy it at his full potential

I uninstalled malwarebytes and i gained 200 mbps
My antivirus is ESET Smart security, but even if i disable it totaly, it change nothing

And there is a fact very strange :

My connection in normal is at 450 mbps
I boot in safe mode i test it and it goes to 950 mbps
I reboot in normal mode and it goes to 850 mbps for few minute
If i reboot normally, it stay to 450 mbps

I don't understand..

I disable all telemetry stuff with "no spy "tool

i did this for disabling windows auto tunning and heuristics :

netsh int tcp set global autotuninglevel=disabled et netsh interface tcp set heuristics disabled

I disabled p2p update sharing
I don't know what to do anymore
Thanks for reading me..

Sounds like the Firewall is throttling it. Leave Autotuninglevel enabled. Do not change that or you will run into issues when the adapter driver has to adjust for bad crc's, etc..

Ok i reset it on normal



Yes i think it's the firewall too, but it seems it's deeply in windows 10 because see i disable my antivirus protection and the firewall protection but the issue won't dissapear, weard no ?

I uninstall NOD32, issue resolved .. But how i do if an antivirus slow down my connection like that ? i don't use ?

Often av doesn't let you go straight out it runs a proxy server to scan everything which takes time
