Looks like there is a bug in VMware ESXi.
Exchange 2013 SP1 on win2k12 r2 on a physical server: no slow upload issue with Outlook.
Exchange 2013 SP1 on win2k12 r2 on VMware ESXi 5.5 U2: has slow upload issue with Outlook.
-tried E100E & VMXNET3 network adapters, doesn't fix the issue.
-only way to fix the slow upload issue is to modify the registry key TcpAckFrequency on the PC
How do I fix this in ESXi without modifying TcpAckFrequency in the registry on the PC?
Thanks
