The Upload Mystery Win10 vs Win11

hi there,

So i have 2 accounts at hosting providers, one in the UK and one in Germany. I am myself located in Europe.

From a long time i always had a relatively slow upload speed to the UK one compared to the Germany one, i thought server infrastructure was slower, more distance, etc .... Just recently they upgraded sever infra on the UK one and there was a nice upload speed increase, NICE!

HOWEVER..................

Recently i've installed Win11 on a new high performance Desktop PC and i tested upload speed again to the UK server, to my great surprise, i was able to nearly max my 100 mbit upload speed (just like to the German server) 10-10.5 MB/sec Upload - same fiber connection, etc which was great!

Now i've rolled back to Win10 and upload speed is back to the "slower" one which is totally bizarre. Meaning 2-3-5 Mb/sec

And even more bizarre is that the server in Germany has always the same "higher" speed whether it's Win10 or Win11.

That leaves me with the fact that there's some setting on the UK server's infrastructure which works best with Win 11 settings or something like that?!?!? Just asked the host but is a mystery. Any ideas?

Tweaks for the network card "Advanced" page ? you can disable like Efficient Ethernet etc - i use 1 GBPS ethernet connection on a 200/100 fiber optic.

thank you!

Different drivers for wireless network adapter?

negative, still the same 1 gbps connection, not using wireless to test this.

this is what they said on filezilla, although speculative:

"As you mentioned a high performance system, maybe the CPU has advanced hardware acceleration features that are utilized fully only under Win11 (due to the CPU coming after Win10). Or, the OS could actively use the TPM under Windows 11 to accelerate crypto algos (as Win11 lists TPM 2.0 as a system requirement). The difference between the servers could be explained by the German server using an older (or just different) cipher algo that does not require the new acceleration for running full speed, while the UK one does use a very new one that's performing slow in software mode only."

what u think?
