I like where VMware is going with how each application is on its' own with 4.0. I'm familiar with this as we came from using the Citrix App Layering (Unidesk) product.

I'm still getting longer login times with App Volumes 4 compared to 2.18. I have also enabled writable volumes for the account we are testing with and used the profile only template. My login time dropped to ~42 seconds even when I assigned 3 packages (Chrome/Firefox/Adobe Reader DC) when using a writable volume with profile only. However from what I've read, it seems we should avoid using writable volumes as others seem to have nothing but issues with them. If I don't use a writable volume I go back up to about ~52 seconds for login with 1 package. If I assign 2 more packages my login goes to about ~1 minutes 20 seconds.

My App Volumes 2.18 setup I still get ~30 seconds login time with 2 AppStacks. So as we are needing to get this rolling and get this out to users, it looks like I'll be going live with 2.18 in our Production environment.

Our users care a lot about the initial login so that is making us lean towards 2.18 for now, even though they have to worry about the longer login only once for the first login of the day.
