Unity Cache Size

I have a scene that I have packed as an asset bundle using:

BuildPipeline.BuildStreamedSceneAssetBundle

Size of the bundle is: 863 KB

When I download the bundle using:

WWW.LoadFromCacheOrDownload

in http://webplayer.unity3d.com/setup/ settings, I can see it is cached for a size of 5.4 MB.

So I suppose it extracts the bundle but still 5.4 MB is too much when the bundle size of 863 KB is considered.

Thinking of 50MB limit for caching license, how can I control the size of the cache or what am I doing wrong here to see a 5.4 MB of cache instead of 863 KB?

Thanks!

Asset bundles are stored uncompressed in the cache. If 50M is insufficient for your game you can upgrade to a cache of whatever size you want. Just contact the sales team to discuss pricing.
