Hi there!

We are going to release the app in several days. Our app has over 1.5 million installs, so this issue is vital for our app.



After Vuforia initialization (which lasts several seconds), the following method is called for each target. Our app contains about 100 markers.

Here is the part of log:

Found Trackable named boost_04 with id 99

UnityEngine.Debug:Log(Object)

Vuforia.StateManager:AssociateTrackableBehavioursForDataSet(DataSet)

Vuforia.DataSet:Load(String, StorageType)

Vuforia.DataSet:Load(String)

Vuforia.DatabaseLoadARController:LoadDatasets()

Vuforia.VuforiaARController:StartAfterInitializationCompleted()

Vuforia.VuforiaARController:UpdateState(Boolean, Boolean)

Vuforia.DigitalEyewearARController:Update()

System.Delegate:DynamicInvoke(Object[])

Vuforia.DelegateHelper:InvokeDelegate(Delegate, Object[])

Vuforia.DelegateHelper:InvokeWithExceptionHandling(Action)

Vuforia.VuforiaBehaviour:Update()

Start Vuforia Engine

UnityEngine.Debug:Log(Object)

Vuforia.VuforiaARController:StartVuforia(Boolean)

Vuforia.VuforiaARController:StartAfterInitializationCompleted()

Vuforia.VuforiaARController:UpdateState(Boolean, Boolean)

Vuforia.DigitalEyewearARController:Update()

System.Delegate:DynamicInvoke(Object[])

Vuforia.DelegateHelper:InvokeDelegate(Delegate, Object[])

Vuforia.DelegateHelper:InvokeWithExceptionHandling(Action)

Vuforia.VuforiaBehaviour:Update()

All this full procedure takes about 60 seconds on Android release build (aab-file).

Herewith, the same process on developer build (Android apk file) takes several seconds. As well as on IOS developer and release builds.

Unity Version 2019.2.14.f1

Vuforia version 8.5.9

Could anyone please help?

Hi,

Could you please provide us a logcat dump with VE initializing?

Thank you.

I also updated Vuforia to 9.2.7 but it did not solve the problem. The startup still takes 20+ seconds.

Thank you for your help and best, friedulia

Dear Support-Team,

thanks for your reply. Unfortunately the method described in the link does not fix it.

I set all the loggings to "none" in the Player settings.

But in the link it does not seem that there is a proper workaround.

Can I update to Vuforia 9.2.7 within Unity 2018.4.23?

Any other ideas?

Thank you very much for your help.

Hi,

I believe you are encountering a known issue. A dev reported on the forum a performance different between ARM v32 and v64, the ladder being slower. ( around 20 sec slower)

If this is the use-case, we addressed it with 9.1 but if you are using an earlier version of Vuforia, please go over following workaround: https://forum.unity.com/threads/huge-fps-drops-from-60fps-armv7-to-25-30-fps-arm64-unity-2017-4-20.682018/#post-5013077

Thank you.
