x7007 4 Posted November 1, 2017 Share Posted November 1, 2017 (edited) Hi, Using Windows 1709 x64 with SolarFlare 10Gb Network card with EIS installed and trying to Enable Microsoft RSC ( Receive Segment Coalescing State ) doesn't enable it with error saying ( WPF Compatibility ) When it's enable properly it should says ( NoFailure ) Could you update your WPF driver to support RSC ? I talked to SolarFlare and they said the WPF driver need to support it or else it would disable RSC till you uninstall or disable it. Please update your WPF drivers with ESET so I can keep using your Antivirus + Firewall , or else it just disable the RSC for me. With EIS it doesn't work, as soon I uninstalled EIS , RSC started working without the WPF Compatibility error. Screenshot attached . The first one is with EIS installed 10.1.235 The 2nd is EIS uninstalled I have yet tried ESET 11 which was just released , but I want to wait for your answer about this. please if you can release a Beta or Pre-Release version so I can test it ASAP ! if it doesn't work with version 11 just yet !

Administrators Marcos 5,259 Posted November 2, 2017 Administrators Share Posted November 2, 2017 Do you have any benchmark results that would show a reasonably lower CPU utilization with RSC enabled? Link to comment Share on other sites More sharing options...
x7007 4 Posted November 5, 2017 Author Share Posted November 5, 2017 (edited) Well, because some brands like SolarFlare doesn't support Large Receive Offload anymore in their drivers . I have it on because I've manage to do it using older driver and then upgrade to newer one while keeping the setting in the advanced options. But RSC is the only choice if I do not have Large Receive offload and the only way to enable RSC is using ESET 11 now . but now that ESET 11 has the newer Window Filter Platform driver it's working. Large receive offload improves a lot , RSC improves even more. it's not about the CPU Usage but more about the DPC while it moves the data . it delay all the other drivers/system while performing the download task over high download speed bandwidth . and the DPC just going over the roof.

x7007 4 Posted November 6, 2017 Author Share Posted November 6, 2017 Still getting WFP Compatibility after using ESET .

x7007 4 Posted November 6, 2017 Author Share Posted November 6, 2017 (edited) Marcos, Eset , Could you make WPF Compatibility drivers please ?> Kaspersky internet Security 2018 is working fine to compare with eset.

x7007 4 Posted November 11, 2017 Author Share Posted November 11, 2017 Any update on that ? did you get update the WFP drivers ? Link to comment Share on other sites More sharing options...
Administrators Marcos 5,259 Posted November 11, 2017 Administrators Share Posted November 11, 2017 There are currently no plans to support RSC. Link to comment Share on other sites More sharing options...
x7007 4 Posted November 13, 2017 Author Share Posted November 13, 2017 I figured the issue. When installing ESET it changes the TCP ACK Frequency to 1 . RSC works fine with that. if I change to 0 to disable. then it says WFP not compatible . Why Kaspersky doesn't need to change the TCP ACK Frequency but ESET does ?

x7007 4 Posted November 19, 2017 Author Share Posted November 19, 2017 (edited) Testing again. What causing the WFP Compatibility to be shown again and again after a while is the Maintain inactive TCP connections . What does it actually do ? what program it can affect ? Can I keep it disabled for performance or compatibility ? Edited November 19, 2017 by x7007 Link to comment Share on other sites More sharing options...
x7007 4 Posted November 20, 2017 Author Share Posted November 20, 2017 It seems that is the cause . Can someone explain this option please ? why it's default set to Off and when should it should be On ? Link to comment Share on other sites More sharing options...
Administrators Marcos 5,259 Posted November 20, 2017 Administrators Share Posted November 20, 2017 We added the option to maintain inactive TCP connections to solve certain issues in the past. If you don't experience any issues with this option disabled, you can keep it disabled. Link to comment Share on other sites More sharing options...

Also another question . Can ESET work without TcpAckFrequency set to 1/Disabled ? because it effect the performance of my connection. When installing ESET it changes automatically the setting. What happens if ESET is installed and set automatically TcpAckFrequency to 1 and I change it to TcpAckFrequency default n/a ? which means it doesn't exist. would ESET won't work properly or causing issues ?

I don't think this will change since with TcpAckFrequency set to 1 the performance is much worse. Honestly, you are the only user that I've heard of where the behavior is opposite.

Honestly, you are the only user that I've heard of where the behavior is opposite. Because when ESET set it from Default n/a which is nore 0 or 1 . then it uses less UPLOAD speed. my connection is 500mbit/10mbit so I am very limited with upload . ESET changing the TcpAckFrequency to 1 uses more UPLOAD speed because it send more upload because how it works . The question is if I install ESET and it changes the registry to 1 , can I set it to Default n/a like it was without ESET without causing issues with the ESET Firewall or protection ?

Administrators Marcos 5,259 Posted November 20, 2017 Administrators Share Posted November 20, 2017 The reason for the change is that Windows will sometimes delay sending TCP ACK to the point that the active connection would stall. Despite numerous appeals and released fixes the problem was never solved completely. This is only happening with ESET's network drivers installed. We're changing this value to force Windows to send ACKs more often as a workaround. It doesn't affect protection. Link to comment Share on other sites More sharing options...

Without the internet Security Firewall , just the ESET Antivirus Edition. Edited December 7, 2017 by x7007 Link to comment Share on other sites More sharing options...

To my best knowledge, we keep information that the value was changed after installation and do not attempt to change it back then. Link to comment Share on other sites More sharing options...
