[gentoo-embedded] Small standard system take 84MB of ram after startup. How to lower memory footprint?

[Kfir Lavi]

Hi,
I have created a small Gentoo system. It is based on glibc.
When it starts, I see use of 84MB and free is 33MB.
Using 'free -m' command.
How can I debug this issue, in order to lower the memory footprint?

Thanks,
Kfir
