- Receive Side Scaling (RSS)
RSS is enabled by default for best networking performance. It is best to set the maximum number of RSS queues to be equal to the maximum number of RSS CPUs.

 

I did it, without having read this post, for my 2 intel cards integrated in my Gigabyte motherboard.
On the other hand, I chose to limit to 1 RSS queue on the entry card and 2 queues that which goes to the NAA player.
HQPlayer uses core 0 and 3 (ASDM7EC). Only core 1/2 and 4/5 handle network interrupts.
Choice validate after LatencyMon tests

Interesting. This is somewhat in line with Taiko Audio's philosophy of assigning precisely defined tasks to specific cores. Did you do it with Process Lasso?

Yes with ProcessLasso but you can do almost the same with taskmanager.

And I use other utilities ..
Have you noticed how the core 0 is always more in demand ?

In fact, Core 0 is the busiest. The settings in the Task Manager are only of a temporary nature, as they have to be set again after each restart.

 

For the Solarflare SFN8522 NIC the manual says:

 

"RSS Base Processor
For a Solarflare network adapter, the RSS base processor is 0 (zero), which means it starts processing on CPU core 0 which is also the default processor for all other general Windows processes and will likely be the default for all other network adapters in the server.
To avoid this unnecessary contention, set the adapter RSS base processor to another processor on the NUMA node the Solarflare adapter is assigned to."

 

In HWMonitor it was easy to see that from Core 6 onwards there was a lower load. I set this value. It seems to be working. 👍

Yes, and it is especially LatencyMon that intrigued me with this imbalance of interruptions between cores.
I tried to distribute but windows itself is not flexible.

So you left the clear thick lid on in the end? Looks nice!

Thank you. Yes, the acrylic glass with a thickness of 10mm breaks the light very nicely.

About the sound: Like the SFN8522 NIC, the sound is three-dimensional, more details can be heard. No sharpness and a deeply graduated bass. Of all these good features, with the X2522 Nic improves a bit. There are no worlds, but if you want the best ... 👍

Excellent report. Is there a specific license we should look for as well?

 

Thanks,

Another report for the latency minimizer. 😁

 

A tip from this forum brought me to the Solarflare XtremeScale X2522 NIC. The front looks almost like the Solarflare SFN8522 NIC.

The back then shows a few more chips.

As usual, the firmware was not up to date. I did that right away.

The BIOS menu was a surprise. The firmware can be set according to the purpose. I chose Ultra low latency.

The connection to the NAS and T + A NAA was established quickly. Unfortunately, the joy was short-lived. The card switched itself off after about 5 minutes. Unfortunately a heat problem. Despite the fan-optimized acrylic glass cover, operation is only possible without a cover. So it has been running stable for days now.

Is the X2522 more or less warm/analogue sounding compared to SFN8522?
 

Also can you confirm X2522 can’t be used with acrylic lid with holes? That could be a deal breaker for many. Thanks!

Great find on those heatsinks! I started looking but did not yet get to ALi ....

What is everyone's thoughts on the latest 500W ATX LPS by HDPlex? I am thinking of going this route instead of DC-ATX 400W + Keces P8. It has 2 DC output for USB cards and whatnot, so seems like a solid all-in-one solution for simplicity and convenience (?)

And the Taiko Audio 500W DC DC-ATX converter shines with a ripple noise of 0.10mV (millivolt).

Hi @StreamFidelity,

 

That is an interesting writeup thanks for posting. Its sound as thought the DC ATX is working very well in your system.

 

The measurement you quoted is interesting, did you make it directly yourself ? If so I wonder if you can say what the conditions of the measurement were ? eg with a DVM an oscilloscope or analyser,  and what were the load conditions for the measurement ?

 

Thanks,

 

OAudio.

No - You can find the measured values at Taiko Audio 😉
