I'm having a strange issue on every desktop that we've upgraded to the latest version of Horizon on. I've upgraded from view 5.1 to 6.1 (or whatever the latest is, I forget). Currently every host is also running ESXi 6. The issue is when we try to access anything network related, such as load a webpage, or access email it takes up to 5 minutes. I've tried with E1000 NIC and VMXNET 3. The desktops are also running the latest version of vmware tools and the horizon agent.
Is there anything obvious I could do to resolve this? Network load looks the same as when it was running 5.1 so I don't believe it could be anything switch related. I've tested many physical desktops/laptops which work perfectly fine, but 2k of our VDI VMs all run slow when accessing network resources. Normal desktop use is normal such as typing in documents.
Let me know if I can provide any more information.
Thank you
