Its clear that the Xbox does struggle to run what I've been running on it with only 64MB of RAM. With 128MB, the accurated 'used physical memory; guage usually floats at around 68MB, which obviously a stock Xbox doesnt have. If you look at the load graphs, youll see that the load is actually extremely low, except for a spike in the middle (accurate at time of posting) which was me updating/ compiling some software, but even this spike is extremely low. Usually compiling would take me up to about 5.00->10.00 load average. I can now run PISG without the xbox going into 40.00 load averages (See its results here). Also, when I'm doing some heavy processing, the SSH no longer becomes unresponsive.

In short, I HIGHLY recommend people upgrade to 128MB if they are running Linux fulltime. Though don't complain to me if you break your Xbox upgrading! Also, remember that Xbox-Linux have a couple of companies that can upgrade Xboxes for you!
