ok, thanks for the rather clear answer ... from experience, I only have tested and witnessed (huge) difference in video compression time (i.e. with ffmpeg2theora) on 64bit compared to 32bit installations ... on sound parts, I must admit I have not realy made tests to compare...
So we will wait for the things from Karsten to happen, of course it is not so urgent I guess, and we'll install 32bit versions on thoses system for now... We'll stay the eyes open for possible code sprint funding, (did you tried http://www.nlnet.nl/ ? ) thanks for all, Olivier.
