Re: benefits of using of ccache?

[Stef van der Made <svdmade planet nl>]

Hi Paul,

While building the full suite of Garnome I see the cache grow until it 
reaches about 1.1GB after several updates. I think that 1 GB is enough 
when you build without using too much of boostrap and bindings.  It does 
speed up the build quite conciderably on my box :-)

Cheers,

Stef
