It has been tested by myself on Mandriva 2006, Mandriva 2007, debian
"a recent one", ubuntu "a recent one", and be others on this list
which reported a working MoGo :).

For the hardware question, 512 Mo RAM is enough in common use, and the
"tree garbage collector" is by default set to use less than 400 Mo
RAM. Of course you can change it to use more RAM.
For the speed, it is difficult to say, but let's say that you loose
20% to go from 2 CPUs to 4 CPUs at same clock. It is an approximate
rule, and it also depends on how long you let him think: the longer it
thinks, the bigger is the tree, the more time it spends in the tree,
the less efficient is the multihreading.
