If it was in Java it'd pause every few seconds for GC.
Thinking about it, though, I imagine that a system like that would be highly parallel (lots of threads and processor cores), and for that you would use a functional programming language like Erlang or Haskell. If you used a language like C++ or Java which allows mutable state, there would probably be a lot more bugs in the Matrix (the only one I remember is deja vu, and that wasn't a coding bug, it was just the time taken for the system to update itself when something was changed). Since their system was also very network-based, I'm going with Erlang.

From within a simulation, can you be aware of when the simulation is suspended? When it is saved? When it is reloaded?
In terms of real life, we could actually be in a simulation. We don't know the laws of physics of the thing simulating our existence, and we certainly can't tell if we get paused, saved/loaded, or if we're taking a long time to compute each keyframe.
EDIT: I don't recall in the movies how time in the matrix compared to time in the supposed real life.

No, I suppose not, but from the outside you would be able to tell.

You're right, it's impossible to tell from within the simulation.

I assume it's supposed to be the same, but I guess it doesn't make a difference since they can't tell anyway. I think it stays in 1999 though because the machines thought that was the golden era of mankind or something (I don't get why they didn't set it in ancient Greece but I guess that would've been a different story).
