Right now I'm running ESXi on two hosts, every for the last 4 Fridays or so (with the exception of the last two) their have been sudden drops in network performance and its happening again. I want to credit it to possibly TCP Offloading, but Im not to sure. I do have a large SQL server thats processing a bit of data daily, and another server doing the same, but they run fine all week. Anyone have any idea where I can possibly pinpoint the issue. Like I said I want to disable TCP Offloading, but can't afford to reboot the server right now. I've attached the graphs if that will do any good.
