Windows slow write performances at 10Gbps speed

#1
Hi, great video and article, here is my issue.
I have a PC and Mac connected at 10Gpbs to a qnap NAS, all jumbo frame enable, and using speed test by openspeedTest, I get the 10Gbps speed no issue.
Now, with the mac, I can get about 800MB/sec write and 1101 read which is not too bad, even if it would be nice to have a bit more write performances
With the PC, I only get about 500MB/sec write and 900 read, clearly there is a bottleneck on the Windows 11 PC somewhere, do you have any idea how to optimze it? I did use the recommended cmds in
power shell
netsh int tcp set global autotuninglevel=normal

Set-NetAdapterRss -Name "10GbE Adapter Name" -Enabled $true

netsh int tcp set global rss=enabled
netsh int tcp set global ecncapability=disabled
netsh int tcp set global chimney=enabled

The last one does not work by the way, but it really did not change anything...
Thank you
