Serious problem with AssetBundle

i put some AssetBundle in StreamingAssets and use WWW load, like:

string path = “jar:file://” + Application.dataPath + “!/assets/” + “myfile.unity3d”;
WWW www = new WWW(path);
yield return www;
Object o = www.mainAsset; // Problem!

When i access www.mainAsset, on Galaxy S4 it work well, but on my other Tablet PC, it will cost 3 minutes!!!

this Tablet PC: CPU: K3V2 4cores 1.2GHz, 1G Memory

how can i improve performance on this Tablet PC?

Are you using uncompressed asset bundles? They load much faster but are larger.

i tried, but no improve…
