Dir. /home/tc uses 70 MB of ram. Is all of this writable files?

[SunBurnt]

I was taking statistics on TC, and I noticed there`s 122 MB ram used after sync and sudo clear-cache.
sudo du -sxm / shows 87 MB used, what`s the other 35 MB of ram used by? The kernel can`t be all of it.

Also the extracted tinycore.gz file is about 17 MB, which leaves 70 MB of ram used by the extensions.
I searched the / file system and found it`s in the dir. /home/tc , most of the used ram`s in the mozilla dir.

Is all of what`s in there writable files..? It seems like a huge amount of config. files if you ask me...

You do have applications running too. And browsers like to create huge caches.
