HOW TO:  Enhance the performance "speed up" the VMware vSphere Web Client in 15 minutes

In my previous Experts Exchange Articles, most have featured Basic and Intermediate VMware and Virtualisation Topics.

If you would like to read my Basic VMware articles,  they are listed here for your convenience.  

During this series of articles VMware released VMware vSphere 5.5 and VMware vSphere Hypervisor ESXi 5.5. These articles are also applicable to VMware vSphere Hypervisor ESXi 5.x and 5.5. For consistency, I have used VMware vSphere Hypervisor ESXi 5.1 through this series.
In this article we will show you HOW TO:  Enhance the performance "speed up" the VMware vSphere Web Client in 15 minutes

I've not included this article in Basic VMware article series, but I'll refer back to this article in the future, when we discuss the installation of VMware vSphere vCenter Server, in the VMware Intermediate Series in the future.

VMware vSphere Web Access was originally released for VMware vSphere 4.0 and vCenter Server 4.0, it was updated in VMware vSphere 5.0, and is now referred to as VMware vSphere Web Client.  As of VMware vSphere 5.5 the VMware vSphere Web Client uses Adobe Flash, and is a feature rich client.

As it's name suggests it's accessed via a Web Browser e.g. Internet Explorer, Firefox, Chrome or Safari.

VMware vSphere Web Client login via web browserMany of the newer features of VMware vSphere 5.5, can only be accessed and configured from the new VMware vSphere Web Client.

Here are some examples

virtual machines of version 10 or higher cannot be edited
Virtual Machines of version 10 or higher cannot use the traditional VMware vSphere Client to edit virtual machines
VMware vSphere Web Client
Big Data Extensions is only available via VMware vSphere Web Client
Access to VMware vSphere Data Protection is only available via VMware vSphere Web Client
vCenter Operations Manager intergration into vSphere Web Client
vCenter Operations Manager has been fully integrated into the VMware vSphere Web Client  
This is excellent news for VMware Administrators, administrators now have a client which can manage a VMware vSphere environment across many different OS platforms, e.g. Windows, Mac and Linux, it brings a new way of working, and VMware Administrators, have to learn new methods of working with the VMware vSphere Web Client to perform VMware vSphere administration.

However, ask any VMware Administrator, about the VMware vSphere Web Client, and you will find that most hate it, and find it terribly slow to use, due to the use of Adobe Flash technology. Unfortunately, as you have seen above,  VMware Administrators, must get used to using the new  VMware vSphere Web Client, because VMware have informed us that the VMware vSphere Client is no longer being developed, and is going away!

I have found a golden nugget of information, that I would like to share, on HOW TO:  Enhance the performance "speed up" the VMware vSphere Web Client.

1. HOW TO: Enhance the performance or speed up the VMware vSphere Web Client

Using the same Web Browser you use to access the VMware vSphere Web Client, go to this website Adobe Flash Player Website Storage Settings panel
Website Storage Settings PanelThis will display a list of websites you have visited using Adobe Flash, and will show the amount of storage reserved for Adobe Flash.
Website Storage Settings Panel - UnlimitedSelect the vCenter Server website, and increase the limit to Unlimited. This is only going to change the amount in kilobytes used. It's not going to be an excessive amount, but this will allow vCenter Server, to store and cache data required. This increases the performance of the VMware vSphere Web Client, and makes it easier to use.

Congratulations, you have successfully Enhanced the performance of your VMware vSphere Web Client
