In the end, it took Dom 2 months to actually read the thread from start to finish. My apologies to Dom for that as one tends to write more freely when hiding behind a pseudonym. I haven't been active in this thread for months and didn't realize that Dom actually "came back." I've since edited out the nasty parts. My vitriol of DCote74 of late was an unwarranted attack. We use DELL Servers with Broadcom 575xx and 574xx NICs (same behavior on both). Last we discussed, to change network adapter o another vendor. So cannot understand that behavior because the main reason for that should be a high load, or latency.
But "zero window" also when only one backup job is running. Interesting: No "zero windows" while SMB transfer. We can bring the throughput to 25Gbit with ntttcp tool. We also checked energy settings, fw, drivers, etc. But I'm not a network expert to say "that's the real problem". So I can exclude network and application - I think. But what we last found out: there is also a "zero window" behavior between direct links between the servers and in ntttcp tests. First I thought, that the application has a buffer issue. Our systems are only used for backup jobs. I was not sure if the dicussed network parameters here (and on many other pages) are relevant for my case. Would you say, that there is a general issue and not only relevant for hypervisor used systems? On theĬontrary, in my opinion, he is one of the most deeply involved Microsoft Windows 10 as well as further details on the problems mentioned above.Ībsolutely cannot confirm, that Dom does not care about the matter. Very recognized MVP has already been called to help to analyze these problems.īe in touch shortly with a few new "tuning tips" for Server 2019 and To pinpoint the problem child who is responsible for this misconduct. The bad news, this deficiency is also present 1:1 in the latest preview of theĪlready shared my findings with Microsoft in Germany and continue to work hard
Network configuration and also the power management of the Server 2019. In addition, I found other suboptimalities in the standard Stack, which, depending on the load pattern, that can lead to a very extreme The good news, I was able to detect several malfunctions in the Windows TCP I have good news and bad news in this regard. Which could explain many of the problems discussed here. Performance problems of the server 2019 and have dug up a lot during this time, Last two weeks in particular, I have dealt very intensively with the
