actually a smart NIC can offload and do packet priority and in the killers defense packet priority of UDP traffic getting more packets on the line faster and in order the windows network stack tends to send the UDP out of order or with a delay which it takes around 10ms of delay to meen the difference of server accepting your headshot you placed with a sniper rifle vs wall behind them. I want to point out servers use UDP packets for target location and shots / spells cast or fired and targeted area along with if there is a target there .
I also want to point out many games use TCP to measure the ping / latency of players world of warcraft for example and uses alot of UDP for everything else so ICMP is not what alot of game servers use to monitor and respond to PING / latency if I remember correctly crysis 2 & 3 / BF3 / Guild Wars 1 & 2 / planetside 2 / Star wars the old republic / alot of the call of duties and many others both MMORPG's and FPS games do so they use ICMP for server to server ping / latency to measure variances and to adjust pipelining and priority for the dedicated servers and such and how they respond and how the hardware itself prioritizes the game data flow.
The reason I know about the world of warcraft thing is I hosted a private wow server for many years and did so all the way to cataclysm and I have family who work for blizzard / EA and have friends in Infinity ward / Activision and a few others and often get into chats with them about such things.
I also want to point this out ICMP is a part of code / packet that is injected into the TCP packets so again TCP is what the games use to monitor ping / latency of players because it is naturally being refreshed constantly because it is usually followed by a response while UDP is is not it comes as it comes and server just accepts the data packets of UDP without any further response.
The killer 2100 offloads the UDP data and bypasses the windows network stack and injects alot more UDP packets into the stream / line in order and faster giving higher successfull chances of your data making it to the game server faster and in order increasing the responsiveness to your shots fired / spells cast and increasing chances of hitting desired target. AGAIN read pages 6 and 7 http://www.kitguru.net/networking/zardon/bigfoot-killer-2100-gaming-network-card-review/6/
they explain and show how the killer 2100 does this better than even Intel smart NIC's and they did the tests in a pretty good manner from my understanding and from my research / experience this has even farther progressed performance wise recently with better drivers / software.
So why dont one of you network tech guys spend a few $ and test this yourselfs can find these for around $45 after done with tests just resell it and get atleast 90% of money back. If you do so let me know I will walk you thru setting it up for optimal testing there is stuff you need to tweak / adjust windows or microsoft tried to block and cripple the killer NIC's from offloading and doing theyre tasks at theyre optimal ability. I believe it may have been microsoft trying to save face like they did with audio offloading / processing which they crippled and killed till this day which was the main point of addon aftermarket sound cards were better sound quality and offloading. I advise a onboard vs addon cards of both Intel and killer and so on try to get a variety if possible to compare it to and make sure that the tests are wide spread and will show a wide variety of results to compare to.
1st step; download and install the latest killer software / drivers http://www.killergaming.com/support/driverdownloadsupport
is theyre website and direct link to the drivers for the killer 2100 and other killer hardware.
2nd step: go into network and sharing center then go to change adapter settings go to killer 2100 network adapter right click go to properties disable Qos Packet Scheduler then hit ok the killer has its own software QOS in the driver software the one you disable is the windows QOS being forced on the killer NIC. If you dont do this windows / microsoft wont allow the killer 2100 to offload or bypass windows network stack meening it is being crippled same as they did with sound cards audio offloading to the sound card rather than being done by computers CPU.
3rd step: go into the bigfoot networks killer network manager software then go to network set the upload / download speed to your ISP sevice speed then go to TCP Protocol Settings put checkmark on TCP NO delay then change TCP ACK Frequency to 1 then reset computer.
4th step: once computer restarts check the killer networks killer network manager make sure it took the settings and check to make sure the step 2 settings are good and then do your tests.
I want to also point out with 50mbs download going ( downloading games from steam and EA's origin along with UPLAY along with patching WOW with P2P sharing enabled ) and such I can see my killer NPU doing 17% or so usage so it is offloading both UDP and TCP with newwer drivers that is 68mhz of the Killer 2100's processor or better known as NPU being used out of its 400mhz highest I have ever seen is 25% NPU usage and that was hardcore file transfers PC to PC and at 109mbs-112mbs so I will say that is pretty good. I am not sure about the amount of the Killer 2100's 128mb of ddr2 ram is being used no way to measure it but I do know most Intel smart NIC's only have like 32mb of it for doing buffering and such which is what the ram is there for.
I also want to point out my killer 2100 is modified and is heatsinked on ram and NPU and any other chip that gets warm. I use ram sinks and arctic cooling MX-4 ( non conductive and has high thermal transfer ) and then hot glue them on corners to PCB and a larger heatsink for the NPU same way and I dont have the stick on ones either. I remove the crap stick on thermal adhesive and lap my heatsinks flat before I use them it is a habit lol.Edited by rickcooperjr - 5/16/14 at 7:35pm
