As Roger wrote to list before few months, experimental version of Tor optimizes RAM usage and I can confirm that. Before I switched to 0.2.1.x branch, my node used +- 2x more RAM (not sure exactly).<br><br>ad "top": Dont forget to buffers and caches. So final amount of actually used RAM by system is:<br>
Used - Buffers - Cached.<br><br>My experience is that blank Debian system take around 10MB RAM. Currently, my home server running Xen dom0, xen-tools, sshd and nagios nrpe takes 47 MB RAM. Tor process for node like yours takes around 50 MB RAM. So I think 64 RAM is enough to run Tor without problems.<br>

The version I used is 0.2.0.33, but I realized that's not the issue.<br>
The mistake I made in reporting these number is that on the i686 box I<br>
used an initrd image in /dev/ram0 which is sized at 128MB. Immediately<br>
upon booting, "free" reports 133 MB of RAM in use just before starting<br>
tor. On the MIPS I used an initramfs image and "free" reports 5MB in<br>
use at the same point. It looks like my i686 numbers are messed up, too<br>
high by 128 MB.<br>
<br>
Thanks for pointing that out. I'm trying to answer the question what is<br>
the minimum amount of RAM required to run a bare minimum linux system<br>
which can support a tor relay/exit/directory node. Suggestions?<br>
