Terrible slow when building to webplayer

I got problem when building my app to webplayer.
It is terrible slow (with ~ 300MB). It took 1minute to build to standalone version but over 10 minutes to webplayer.
I think the problem come fromo the LZMA compression.
How could I turn it off when build to webplayer for debug?

I don’t know of a way to disable LZMA but you could consider separating your assets into different asset bundles if you own Pro. Only the main .unity3D contains the logic / code for debugging.

Asset bundles looks like the best solution at this time.
But I don’t know why Unity force using LZMA compression even that is the cutting edge technology.
They should allow developer choose their way, just put it as an option is better
