ccache for windows

Hello

ccache for windows under cygwin is working. That's a fact.
ccache is provided as a binary in the dev-tools repo.
As provided by kendy on  
http://artax.karlin.mff.cuni.cz/~kendy/blog/archives/monthly/2011-04.html,  
I set it and my config_host.mk confirmed it.

But is it normal that ccache on 3.6 branch only uses 3Gb ? I find it very  
low, compared to all binary files produced.

Could someone on linux give its ccache stats to compare ?
Kendy, what's your opinion ?

Thanks all
