Improving WebGL player execution performance

We are looking at a number of ways to improve performance (LZ4, gzip, Optimizing WebGL player, etc.), but I was wondering if anyone has seen the following:

The bulk of time is spent downloading WebGL Player + Model (44%) - which makes sense
The second most time consuming area is player execution before our 3D model is rendered (43%) - ??? (Pic attached)

Any suggestions on how to improve player load times and/or how to force caching on Chrome/Firefox?

Thanks,

Tom

Try put as many of your resources as possible into Asset Bundles, so you get a small data file to load, and download asset bundles as content is needed.
