Solved Slow ESXi Flex UI experience (6.5 update 1)

[Emad R]

So I updated my standalone host ESXi to the latest.

Anyone noticed that Flex UI is still slow, especially when you are using it remotely. I noticed that if i connect to the UI directly using Public IP:Port and opened VM setting page, it takes much longer than
Logged in remotely like above then opened console VM of any VM hosted then opened the private IP of that host then edited the VM settings.

Seems rather stupid. I really hoped the latest update would help things. Actually it made it worse, sometimes I use the Vsphere C# client and in the latest update they completely blocked it, viewing VMs was much faster using it, now I get this :

NVM, forgot about VMware Remote Console (VMRC), which is the optimized way of connection to VM GUI console, download it now.

I think vsphere C# client currently is VMRC in some minimal way. At least one is still actively developed. (You cant connect to an .iso file using webclient flex without uploading the whole .iso file to the host, however with the older C# client and newer method VMRC this can be still done).

That said, we lost the export to .ova or .ovf easier method compared to web ui export which gives you the .vmdk file as is.

A warning message appears after you install the desktop vSphere Client for Windows, and try to connect to an ESXi host
The desktop vSphere Client was deprecated in vSphere 6.5 and is no longer supported. When you try to connect to an ESXi 6.5 host, the following warning message appears: The required client support files need to be retrieved from the server "0.0.0.0" and installed. Click Run the installer or Save the installer.
In this case use the VMware Host Client to conduct host management operations.

I have nothing against using the newer method, it just that it slow.
