Speed Up Your Horizon View Operations

How to speed up your Horizon View operations, you might ask? Well, you don’t have to buy an all-flash storage system or beef up your ESX hosts.

VMware Horizon View Administrator has some settings on max concurrent operations with vCenter and VMware View Composer. Increasing some of those settings can decrease the time of those operations, however when decreasing those settings, you can limit the amount of IOPs pushed to your underlying storage system, too.
