Ran into this again today. Thought we were done with it. New customer install on VMWare 8. As soon as we tried to connect over Citrix performance just tanked. But RDP sessions seemed to be ok. When we were copying the AOT files it took 8 minutes to copy 70k. Ran the offload disable and it immediately fixed it. Microsoft is saying the latest vmware tools should fix it, but they were pretty far up to date with them. So if you have long authentication, try this first. https://docs.jeffriechers.com/Microsoft/24h2-windows-11-and-server-2025-vmxnet3-issues/

Are there any other tells, outside of the resultant slow xfer speeds/extended logons? Something that shows up in perf monitoring or something I can trigger off for detection in our environment? (I'm curious about any other file servers outside of my EUC space) We're on ESXi 8.0.3, 24859861, VMWTools are current 12451
