Inconsistent and slow logins with any version of Appvolumes

‌Hey everyone,

We were running Appvolumes 2.10 and logins were 30+ seconds depending on the number of stacks assigned to a user. In some cases (Visio as an Appstack), logon times would shoot to in excess of a minute. We then upgraded to 2.11 as part of a Horizon 7 rollout (with vSphere 6 U2) and the logon times increased! Ouch! All areas of the build (the core is very vanilla) were reviewed alongside the hosts, storage, network and DB, but with no obvious problem areas. Each time this was raised with VMware, it was acknowledged that certain parameters that were applicable in 2.10 were no longer acknowledged in 2.11 and as there were product limitations for 2.11,  wait until 2.12 and there will be vast improvements!

Well, like others in the forum, during testing of Appvolumes 2.12, we are still seeing yet further slow down of logins!

We managed to improve the speed by dropping SSL, (setting to use port 80 from agent to manager), but the overall result is that logins are no better than where we stood before.

Interesting and unsurprisingly, stopping the svservice (AppVolumes) brings us back to circa 15 sec logins. However, just running the service even with no user stacks assigned adds about 10seconds to a typical logon so there seems to be an effective heavy penalty for it to merely check for user assignments, let alone attaching anything.

Im going to start investigating hardcoding requests to specific domain controllers in preference to using the domain fqdn in the configuration to see if that changes anything too. Will report back.

If anyone else has any similar experience or problems, please let me know as for us, 2.12 was considered to be the last roll of the dice for Appvolumes in preference to a rivals offering that seems capable of cutting our current logon times in half which for a userbase of 1000 multiplied by 15 seconds is the equivalent of 250minutes of lost productivity each time all users log on!

Thanks

Andrew

Ray,

I'm not sure how to do what you describe in the first and second paragraph.  I tried looking in both the vCenter client and through the browser and didn't see anything.  Is the EnforeceSSLCertificateValidation changed on the template?

Yes you need to change the EnforeceSSLCertificateValidation setting on the golden image.

Regarding the VCenter issue. When you log in to your machine a command is being send from the manager to the VCEnter server to add the appstacks. If you look at your VCenter server console (if you use the webpage you need to refresh off course) that the machine is bing reconfiguredm, the disks are being added. If you set up the option in AV Manager to attach appstacks on the ESX host itself you need to log into the ESX hosts to see this reconfigure taking place. The machine you log into is being changed and VCenters shows this info in it's console.

It's a registry entry for the App Vol agent - amend it in your gold image as follows to disable:

HKLM\System\CurrentControlSet\Services\svservices\

EnforceSSlCertificateValidation: 0

alsmk2,

Is the EnforceSSLCertificiateValidation entry supposed to be in ssvservices or one level down in Parameters?

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\svservice\Parameters

to disable it's reg_dword value. switch it to 0

or during installation of app volume agent you can disable verification of SSL by checking option to disable certificate validation with app volume manager.

Ray,

I do have the EnforeceSSLCertificateValidation set as you described.  The information that I gave you was gathered EnforeceSSLCertificateValidation set to 0.

^^ this also didn't fix my issue

If you want to pull logs check out VMware Logon Monitor

See what is running at log in and see what's the issue. I have an open issue with VMWare about this going on over 3 weeks; I'm hoping to hear some good new back soon. Would love to fix my issue and share what worked with others

I'm guess we will have to wait til 2.13 comes out with the bug fix for the ongoing issue.

Add us too.  We have inconsistent performance with AppVol as well.  We have tried the suggested fixes and have not seen any performance increase. We are on 2.12.0.70 and I have built new base image with just AppVol to test the login and we continue to see slow performance.
