    Bump, are you aware of the issue and is this being worked on? Do you want repro projects for Unity 4 and 5?

    Android seems to me messed up big time in Unity 5x releases, not sure why a blind eye being taken here, this probably linked to bad fps on android 5x, yet each patch release so far very small fixes..seeking some Hardcore internal fixes

    I logged a new bug report with APKs for both Unity 4 and Unity 5, case number 701873.

    I had a look at the issue today and noticed that the first Resources.Load has comparable performance to Unity 4.6. All subsequent calls to Resources.Loads for the same asset are significantly slower compared to Unity 4.6. I'm working on a fix for that.

    @iivo_k, is this also what you are seeing or are there known cases where even the first load is significantly (let's say > 10%) slower in Unity 5?

    We ended up manually caching all the things we load with Resources.Load in the first scene which pretty much fixes the load times, so that would seem to be consistent with your finding.

    I have the similar problem when use Resources.LoadAsync, even use latest Unity 5.3.4p1.Resources.LoadAsync is 10x or more slower than Unity 5.2.4f1.
    But if I create a new project for test aysnc load some prefab, was't find the same problem.But it's always in our teams's project.

    At least at Unity5.3.3f1,
    I found that the first Resources.Load of a relatively complicated prefab is too heavy on Android, but no problem on PC.
    Is this going to be fixed?
