Hi all,
I'm testing an E810-XVV-2 dual port network card and I'm facing really bad performance compared to an old (and unfortunately obsolete) X520.
At the moment I need just 10Gbps links.
Under Windows 10 64 bit 22h2 (desktop) I want to use the two ports of the board to read from 12 gigabit cameras connected to an Aruba 2730F switch. Each port of the board read 6 cameras (about 5Gbps). Note: these cameras sends frames using 8K UDP telegrams (i.e. a lot of small telegrams).
I usually does not tweak too much the driver settings: I just enable the jumbo frames, disable all the CRC offloading options and increase the number of receive buffers. All the other options, in particular the RSS and the number of receive queues, are kept to their default value.
Unfortunately this board seem to ignore what it is set as "number of receive queues" and always use 1. As you can see the default is 16
but when I check in the powershell the actual number is 1.
When I start the software to grab from the camera is see that all the load is handle by a single CPU thread.
I have the same behaviour in two different PCs with different motherboards and processors: a single i7 processor MB and a dual Xeon processors MB.
Any hint to get this setting to a value different from 1: simple a single CPU thread is not able to handle all the interrupts for the incoming telegrams.
Regards
Giovanni

Hi.
Unfortunately the NIC device again to limit the number of RSS to 1.
On friday during my test, without any apparent reason we started to loose packets.
When I check the nic, i found this
The number of used Rss queue change from 4 to 1 and there is no way to change this value.
Today I delete the device from windows and then install them again but I can't have the same results as friday morning!
Any suggestion?
