The server would not have any problem serving a large number of users
on that platform. You may want to disable address notifications in the
current implementation.

Your main issue would be initial block download time, given the
current block forward sync. You would probably also have to disable
write flushing or disable transaction relay. Otherwise the possible
inability to keep up with network transactions can cause you to fall
behind. The 8GB RAM would certainly help. The memory-mapped file
implementation is much better with more RAM and I consider 8GB a good
minimum. An SSD would help, but not sas much as the RAM.

Unfortunately I don't have numbers yet on client-server performance,
but it is quite impressive from what I hear :).
